The world's top politicians, economists, businesspeople, and celebrities descended on Davos in Switzerland in January for the World Economic Forum's annual meeting.

Discussions at this year's event ranged from the threat of automation to jobs, Brexit, the lack of clean water in many communities, and what a Trump presidency means for the world. 

Arianna Huffington, cofounder of The Huffington Post, is a long-time Davos attendee. This year she was attending in a new role, as CEO of Thrive, her new wellness startup.

Huffington sent us her photo diary of her busy week taking part in panels, being interviewed, and speaking with dignitaries high up in the Swiss mountains.

MONDAY, January 16: Snow and a glimpse of sun greet Huffington and their team as they make the drive in to Davos.

Huffington spoke at the Financial Times/WiPro Executive Dinner Forum about our relationship to technology in the "Second Machine Age" with Royal Dutch Shell chairman Charles Holliday, founding president of Google China and venture capitalist Kai-Fu Lee, CEO of Wipro Abidali Neemuchwala, and ABInBev VP of Sustainable Development Andy Wales.

Huffington said: "I loved spending time after the panel with Kai-Fu Lee whose inspiring story I wrote about in 'Thrive.' He was diagnosed with cancer in 2013, and it was his wake-up call — instead of continuing to 'compete with others to see who could sleep less,' he started prioritizing his health and wellbeing and went on to write an amazing book 'Finding Life in Death'.”

Tough Mudder is making its first steps towards becoming a fully fledged lifestyle and media company.

For the uninitiated, Tough Mudder is an 10 to 12 mile endurance race in which participants have to overcome a number of obstacles that change each year — ranging from high climbing walls, dark muddy tunnels, to walking through wires that emit electric shocks. 

More than 120,000 people participated in the UK Tough Mudder events last year, including its CEO and founder, Will Dean.

But Dean is aiming for half of the company's revenues coming from non-ticket sources in the next three to five years. In 2015 the company generated $100 million in revenue, Dean told Business Insider.

Its new partnership with UK TV channel Sky Sports Mix, announced on Friday, will give those who haven't yet participated in the race a chance to experience it on their TV screens.

In the seven years since it was founded, Tough Mudder has come a long way. In 2010 it was simply a company that held three obstacle races for brave athletes. Now the brand reaches tens of millions of people around the world and raises millions of dollars for charity. Dean talked Business Insider through its growth story and what he is planning for the future. 

The first look at Tough Mudder's partnership with Sky will air on January 24.

The multi-episode TV series, which already aired in the United States on CBS, follows all the competitors in the most gruelling of its 2016 events, the Toughest Mudder race.

The winner of the 2016 race was the Brit Jon Albon, who was the first-ever participant to complete 105 miles and won prize money of $100,000.

More content is already planned to air on Sky after this series is over. There will also be five digital shorts on Sky showcasing the regular Tough Mudder competitors, including one who battled cancer.

"We talk a lot about Tough Mudder being a tribe, being a nation," Dean said "I believe a lot in the values of teamwork and camaraderie and helping people get through things together." 

Content creation makes up one of the core pillars of Will Dean's growth strategy for the future of Tough Mudder.

The partnership with Sky Sports is the only the first step in growing its content production capabilities. It's also in talks with production companies in the UK to develop regional-specific content.

Online formats have also become a key part of its content production capabilities. Tough Mudder saw 42.5 million viewers live-stream the events and it is working with Facebook and Snapchat to develop new formats and ways to showcase the stories around the events.

Growing its sponsorship and product licensing portfolios is something the company hopes to achieve through the content it produces. One Tough Mudder sponsor, the American footwear company Merrell, now produces Tough Mudder-branded shoes.

As a non-traditional sport, it has been more difficult for Tough Mudder to land bigger name sponsorships than mainstream sports but that is changing with the growth it has seen.

The US Army sponsored and co-produced the show on CBS and the company counts Jeep and cider brand Kingstone Press among its British sponsors.

It's not over for Dean, who has big ambitions to continue Tough Mudder's international expansion.

Tough Mudder is currently present in 10 countries, including the United States, Australia and China and it hosted its first event in Dubai in 2016. 

Dean wants to nearly double the presence in two years, to 18 markets. 

He strongly believes that as the event grows people — who pay up to $200 to beat the obstacles — will come.

"Experiences are the new luxury goods," he said. The rapid growth of Tough Mudder is a testament to that.

Tough Mudder held three events in the year it launched. Two years later, in 2012, it had organized 35 around the world. 

Travis Kalanick may be the public face of Uber, but he hasn't built the company by himself. 

Like any chief executive, Kalanick leans heavily on his team and direct reports to manage all parts of the business, from people operations internally to putting out regulatory fires externally. 

As Uber faces challenges on all fronts in 2017, here's who is leading the charge internally to make transportation "as reliable as running water."

Jeff Jones is Uber's president of ridesharing.

When Travis Kalanick asked Jeff Jones how well he did on his TED talk, the then-Target CMO gave him a B-minus and told him he needed to fix his talking points. 

That's harsh feedback for Kalanick, but also a valuable insight. As Uber has tried to rein in its free-wheeling city offices, it's needed to fix its global branding problems. 

In August, Uber announced that it had poached Jones from Target to become its president of ridesharing, overseeing all of its operations, marketing, and customer support.

Amit Singhal oversees all of engineering and is a special advisor to Travis Kalanick.

Google's former search chief, Amit Singhal, came back out of retirement in January to join Uber as its new SVP of engineering.

In the role, Singhal, who spent 15 years at Google leading its search teams, will be directly advising Uber CEO Travis Kalanick and Anthony Levandowski, the head of Uber's self-driving divisions. He's in charge of overseeing engineering on Uber's marketplace and maps teams — two key departments that touch the core of Uber's business.

Anthony Levandowski is in charge of building the self-driving cars of the future.

Anthony Levandowski's self-driving car work was famous before he got to Uber. His self-driving motorcycle, Ghostrider, is already in the Smithsonian. He'd been researching autonomous vehicles before he got to Google then built the company's first prototypes. Then Levandowski left Google to start Otto, a self-driving truck startup. In August Uber purchased Otto and all of its employees.

Now, Levandowski is the leader of Uber's autonomous vehicle efforts, reporting directly to Kalanick. He's in charge not only of Pittsburgh, where Uber's Advanced Transportation Center is located, but also the offices in Palo Alto and San Francisco. And Uber isn't only thinking about self-driving cars, it's going to continue Levandowski's work with Otto and go into the trucking industry as well as delivery.

Thousands of workers will be heading to a new job this month, excited and nervous to prove they've got what it takes.

For all those newbs hanging their coats on a new office chair, that means it's time to get to work.

"The first three months of any new job are an extension of the interview process," says Amanda Augustine, career advice expert for TopResume. "From the first day, you need to be on your game."

Here's what the most successful people do that first week in a new job:

SEE ALSO: 19 things you should never say on your first day at work

DON'T MISS: 29 things you should never say to your boss, even if you're friends

Take the initiative to meet people. Say hello in the elevator, kitchen, or bathroom. It will pay off in the end.

"It could be a fast-paced culture, and they don't have time to come to you," Augustine says. "Start with the group that's closest to you, the people you're directly working with." It will be in their best interest to get you started on the right foot, because your work will directly affect theirs.

Soak in as much as possible in that first week. If you plan on making any big changes, you need to first understand how things are usually done, and you need to earn the team's trust. 

"Win them over by taking the time in the beginning to learn how things are done and why, so when you want to make changes, you can build a strong argument that your team will support," Augustine advises.

No one likes a know-it-all, and odds are, even if you're the most experienced worker in the world, you don't, in fact, know it all.

When a new colleague or boss offers you help or advice, take it. Never counter with, "Well, in my old company, we did it this way." People really hate that.

Even if you already know what you're doing, showing you're open to advice strokes people's egos a little (and maybe even pacifies feelings that you're a threat) and can help you down the road when you actually do need some help.

The new US presidency of Donald Trump, who was inaugurated on Friday, is sure to divide Americans, coming as it does after a contentious election. But in Hollywood, it's putting many stars on the defensive.

From Michael Moore and Alec Baldwin to Katy Perry and Shia LaBeouf, stars on social media and the real world showed their disappointment in the inauguration of Trump. While others kept silent and some, of course, like the artists 3 Doors Down and Toby Keith, even performed for the inaugural events.

Here's how major stars in Hollywood reacted to the inauguration of President Trump:

Netflix surprised Wall Street on Wednesday when it reported fourth-quarter earnings and subscriber growth.

In the US, net additions totaled 1.93 million, much better than the consensus forecast among analysts of 1.38 million and Netflix's own prior estimates. Earnings per share were $0.15, two cents above the median forecast.

Netflix's performance drove its stock higher in after-hours trading. On Thursday, it hit an all-time high of $143.45, up by 6%, in the first few minutes of trading.

The streaming service is making a major push outside the US and investing heavily in original content that works for audiences everywhere.

"We are in no rush to push margins up too quickly, as we want to ensure we are investing aggressively enough to continue to lead internet TV around the world," the company said in its earnings letter.

Below are some analysts' reactions to the earnings results and their ratings of the stock.

Jefferies: BEARISH

Rating: Underperform

Price target: $95 (from $80)

Comment: "While the international subscriber growth will drive the stock higher, we note cash burn remains above expectations, with fixed cost leverage elusive," said John Janedis.

Credit Suisse: NEUTRAL

Rating: Neutral

Price target: $143

Comment: "For the longer term, Netflix will be looking to show a greater balance between growth and profitability — which to us validates the long-term investment thesis for its international and newer cohorts to follow along the margin expansion trajectory of the US," said Stephen Ju and Christopher Ford.

Macquarie: NEUTRAL

Rating: Neutral

Price target: $130

Comment: "We remain cautious on some items we have discussed at length in previous notes, namely rising content and other costs, and concurrent FCF [free cash flow] burn in the face of rising competition, but subs are what drives this stock and for now the sub additions are covering these," said Tim Nollen. "As such, we are upgrading the stock from underperform to neutral."

Crossover SUVs are hot right now, and the Honda CR-V is a worthy contender in the compact segment.

Honda's CR-V has posted seven straight years of sales gains and was the automaker's most popular vehicle in 2016. As I make my way through different SUVs, like the Subaru Forester and the Nissan Rogue, it only made sense to take the CR-V out for a spin too.

The CR-V is a comfortable and easy drive for someone interested in a reliable ride without a lot of pomp and circumstance. Scroll down for a closer look:

SEE ALSO: The biggest allure of the 2017 Nissan Rogue is the tech inside

DON'T MISS: Subaru's 2017 Forester is still one of the best crossover SUVs you can buy

I took the Honda CR-V on a road trip from New York to Boston to get a real sense of how it performs during long drives and in heavy traffic.

The CR-V starts just above $24,000, but the Touring model that I took for a spin costs $33,695. That's a little pricier than the Nissan Rogue SL Premium I recently drove, but still competitive.

The 2017 model is a bit larger than the previous generation at 180.6 inches long with a 104.7-inch wheelbase. It feels more like a traditional SUV than a crossover.

Donald Trump isn't shy to tout his distaste of regulations.

Since he kicked off his presidential campaign in June 2015, Trump has derided Obama-era financial regulations as "bad for business" and responsible for America's slow-growing economy.

He even promised to eliminate two regulations for every one enacted during his tenure as president.

Most Wall Streeters views Trump's anti-regulatory stance as a tailwind for the financial services industry.

Octavio Marenzi is the CEO of Opimas, a management consultancy firm focused on capital markets. He told Business Insider that Trump's victory was an early Christmas present for banks and other financial firms.

"His win signaled that most of the financial regulations and requirements on the books today will for the most part be scaled back to what they were before the financial crisis," Marenzi said.

"This isn't necessarily going to translate into a golden age for banks, but it will be a normalization of the business environment. They've been battered by regulations and now we are finally going to see a more healthy environment," he said.

"Our analysis shows that efforts to deregulate could redirect more than $25 billion in capital in the financial services industry over the course of the next 18-24 months," Opimas cofounder Medy Agami added.

Business Insider breaks down the four regulatory actions Opimas think Trump will take and the degree to which they will benefit Wall Street:

SEE ALSO: Want to get ahead on Wall Street? Here's everything you need to know to land your dream job

1. Elimination of the Volcker Rule - $6 billion

Marenzi and Agami said that the Volcker Rule will likely be the first regulation on the chopping block now Trump is officially president. That's because all the president-elect would have to do, essentially, is tell regulators to stop enforcing it.

The rule, which is the namesake of former Federal Reserve Chairman Paul Volcker, has been the bain of American bankers since its inception in 2013 when it was implemented as means to prevent future financial crises.

According to Marenzi and Agami, repealing the Volcker Rule will save investment banks approximately $6 billion.

"The implications will be significant for large investment banks since dropping the rule would generate additional revenue and profitability streams," they said.

"There is also significant evidence that repealing The Volcker Rule will increase liquidity in various asset classes—fixed income, equities, commodities, foreign government debt, etc.—by enabling dealers to hold inventory that has long-term demand from clients that would otherwise not be allowed," they added.

Steven Mnuchin, Trump's Treasury Secretary nominee, said in a confirmation hearing that he supports the Volcker rule, but "there needs to be proper definitions around the Volcker rule so that banks can understand exactly what they can do and what they can't do, and that they can provide the necessary function of liquidity in customer markets."

He cited a paper from Federal Reserve staff released in December that found that the Volcker rule had a negative effect on corporate-bond liquidity, or the ease with which buyers and sellers can find each other. 

2. Reductions in capital and liquidity requirements - $19.84 billion

According to Marenzi and Agami, significant reductions in capital and liquidity requirements, which were enacted in order to prevent the type of risky lending that some say was the impetus of the housing crisis, will free up banks to ramp up their lending.

"It will free up nearly $20 billion in unproductive capital over the next 18-24 months that banks are hoarding and could redirect to other areas," they wrote.

"These regulations will be the most difficult to scale back since they are globally implemented and compelled banks to build myriad models and retain armies of risk and compliance teams," they added.

Mnuchin previously told CNBC that the new administration planned to "strip back parts of Dodd-Frank that prevent banks from lending."

3. Say goodbye to the Consumer Financial Protection Bureau - $1.4 billion

The five year old watch dog agency could potentially meet its demise during the first term of the Trump administration, according to Marenzi and Agami. And that's great news for banks.

"The elimination of or serious reduction in CFPB regulations will mean a potential savings of nearly $1.4 billion for banks," they said.

Republican lawmakers have been pushing for the removal of Richard Cordray, director at the Consumer Financial Protection Bureau.

Hashtag. Metrosexual. Occupy.

Those three words have one thing in common — they've all been named "Word of the Year."

Every year since 1990, members of the American Dialect Society have gathered at their annual convention — once called "the Super Bowl of linguistics"— to crown the word that defined the year. The linguists and lexicographers vote on words based on their predominance in headlines and widespread use throughout the country.

Anything considered a "lexical item" can be nominated, meaning multi-word phrases like "dumpster fire"— named 2016's Word of the Year earlier this month — are fair game. The same goes for hashtags, prefixes, and even emoji.

Because each Word of the Year is closely tied with the era that spawned it, looking back at the list of every winner is like flipping through a yearbook of the past quarter-century. There's the surge of Internet-related words like "cyber" and "information superhighway" in the early 1990s and a string of political words like "chad" and "weapons of mass destruction" that reflected the climate of the early 2000s. 

More recently, tech words like "tweet" and "app" have dominated the vote, demonstrating how much the internet has influenced our language.

Take a look at every Word of the Year, and take a trip through time.

SEE ALSO: It's official — the 2016 Word of the Year is 'dumpster fire'

2016 — dumpster fire

The American Dialect Society chose "dumpster fire," a metaphor suggesting a poorly-handled or out-of-control situation, as 2016's Word of the Year on Friday.

The phrase saw a surge in popularity on social media to describe one of the most chaotic years in recent memory, which featured a bitterly contested US election, a stunning Brexit vote, and numerous high-profile deaths.

2015 — they

The word "they" has existed in English for nearly a millennium, but it wasn't until last year that it started to gain traction as a singular, gender-neutral pronoun. The flexible pronoun can be used when "he" or "she" doesn't suffice for people who identify outside the traditional gender binary.

2014 — #blacklivesmatter

2014 marked the first time a hashtag was named Word of the Year.

With the vote, linguists acknowledged the power of hashtags to convey social and political messages, as #blacklivesmatter did in addressing the deaths of African-Americans at the hands of police.

Henrik Jeppesen is a 28-year-old Danish travel blogger who's visited every country in the world.

Despite being a full-time traveler, Jeppesen says he has only spent an average of $20 a day for his trips so far — in large part by being economical and getting sponsorships from airlines and hotels.

"The world is a very hospitable place," Jeppesen tells Business Insider. 

Along his journey, Jeppesen has developed a following as a low-budget travel guru. You can follow his travels on Facebook, Twitter, Instagram and his blog.

We spoke to Jeppesen to hear his story:

SEE ALSO: This 'homeless' guy flies first class for free and says anyone could do it — here's how

Jeppesen grew up in a remote area of Denmark called Thy that has a population of just over 40,000 people. From an early age, he made traveling and seeing the outside world a priority in his life.

At 14, he set a goal of visiting 50 countries in his lifetime. That soon changed to 100 countries, before he eventually decided to just go for every country in the world.

He started saving and looked for ways to travel cost-efficiently. He took advantage of local couch-surfing networks and hitchhiked thousands of times. Sometimes he ended up sleeping in public spots, like a bus station in Niger. “The world is a safe place to travel,” he says.

These points are all broad principles. However, if your new relationship ticks the four boxes below, it's reasonable to assume it has the potential to be a nurturing, cohesive long-term partnership.

If your relationship doesn't tick these boxes, you may need to be more aware of whether your current feelings might change in the future.

SEE ALSO: Relationship experts reveal 6 secrets that help power couples stay together

1. You like each other's extreme traits

Which is more often true: "Opposites attract," or "Birds of a feather flock together?"

In general, it's the latter. People really do tend to partner with others who are similar to them and who share their values.  

Of course, this is a generalization. It's easy enough for us to think of relationships that work despite differences (e.g., Democrats and Republicans, vegetarians and meat-lovers, extroverts and introverts). Where shared inclinations and values tend to be most important, though, is if one or both partners is very extreme in a certain area.

For example, my spouse and I are both extremely frugal. We drive most other people nuts with our resistance to spending money. Most other potential partners would find either of us difficult to live with because we're on the extreme end of the normal curve in this regard.

Extreme opposite traits can initially attract you to someone — for example, a shy, quiet person attracted to someone who has hundreds of friends and is an expert social networker.

However, the more extreme the other person is in a particular regard, the more likely it is that you'll find your differences annoying in the future. Non-narcissists initially attracted to a narcissist's charm is one particularly common example of this pattern. 

When your partner has any extreme traits, you don't need to be as extreme as they are, but it's easier going forward if you're not the complete opposite.

2. Your partner is warm, trustworthy, and dependable

Everyone has their priorities for what they want in a partner. Some people value looks more than money or status, while for others, it's the reverse. But despite differences in people's particular ideals and priorities, almost everyone — both men and women — wants a partner who is warm, trustworthy, dependable, and reliable. 

If your partner is warm towards you and other people, that's a good sign. Likewise, if they're emotionally stable and dependable, that's also a good sign. If they're aloof or narcissistic towards others, but nice to you, that's a potential warning sign: Their treatment of others may be more revealing of their true colors.

3. You and your partner have roughly equal 'mate value'

Research shows that love isn't particularly subjective: Even relative strangers are usually fairly reliable in rating someone's "mate value," i.e., desirability. People also usually have a rough idea of their own mate value.

Problems can occur in relationships when the partners have vastly different objective mate value. We've all seen celebrity marriages in which an attractive, wealthy individual marries someone who doesn't appear to even have a job. Having a partner with lower mate value than yours may be initially attractive, but the sheen typically wears off after time (as we see when such celebrity couples break up).

The reality is that wealthy or attractive people tend to marry other wealthy or attractive people. One might imagine that everyone would want a partner with "10/10" mate value, but this is often stressful due to what evolutionary psychologists call fear of "mate poaching"— if your partner is, say, Maria Sharapova or Serena Williams, chances are you're going to be worried about losing your lover to a poacher. 

In general, then, having a partner who has roughly equal mate value to you typically makes for the smoothest, most enduring relationship.  

[Note: These are principles of evolutionary psychology. They can seem a bit crass in the modern world, but research shows that they are generally true.]

Sure, we all know that an Ivy League education, a stint at a blue-chip firm, and stellar sales skills can help us get ahead. But it may surprise you just how many other, seemingly random variables can contribute to your professional success. 

From the month you were born to your comedic timing, the weirdest quirks can affect how successful you'll ultimately be.

We combed through research on success to identify 25 surprising things that can influence your career trajectory. While some factors can be sought out, others are beyond your control.

DON'T MISS: Parents of successful kids have these 12 things in common

Defiant, rule-breaking kids often grow up to earn higher salaries

Recent research suggests there's a connection between rebelliousness in adolescence and earning a high income later in life.

In 1968, nearly 3,000 sixth-graders living in Luxembourg took intelligence tests and answered questions about their feelings toward school. Their teachers also filled out questionnaires about the students' behavior. At the time, researchers assessed the students' family background as well.

In 2008, researchers revisited this data in order to see which childhood traits predicted career success and income. They were able to get in touch with 745 of the students, who were now about 52 years old. Perhaps unsurprisingly, more studious kids (as rated by teachers and by the kids themselves) went on to land better jobs.

But the researchers were surprised to find one childhood characteristic — beyond IQ, parents' socioeconomic status, and the amount of education the students attained — that predicted higher adult income: rule-breaking and defiance of parental authority.

Parents' high expectations for their kids tend to matter more than income or assets for their child's success

Using data from a national survey of 6,600 children born in 2001, University of California at Los Angeles professor Neal Halfon and his colleagues discovered that the expectations parents hold for their kids have a huge effect on attainment.

"Parents who saw college in their child's future seemed to manage their child toward that goal irrespective of their income and other assets,"he said in a statement.

The finding came out in standardized tests: 57% of the kids who did the worst were expected to attend college by their parents, while 96% of the kids who did the best were expected to go to college.

That parents should keep their expectations high falls in line with another psych finding — the Pygmalion effect, which states "that what one person expects of another can come to serve as a self-fulfilling prophecy" — as well as what some teachers told Business Insider was most important for a child's success.

Being married is linked to higher salaries for men and lower salaries for women

A recent study finds that men experience a "marriage premium": Their salaries generally go up when they get hitched. Women, on the other hand, tend to see their salaries go down when they tie the knot.

Specifically, married men between 28 and 30 years old earn about $15,900 more per year in individual income compared to their single counterparts, while married men between 44 and 46 years old make $18,800 more.

And although these findings were not statistically significant, married women between 28 and 30 years old earn $1,349 less per year in individual income than their single counterparts, while married women between 44 and 46 years old earn $1,465 less.

In November, President-elect Trump and his wife Melania announced that the family will keep their son Barron enrolled in his New York City-based day school rather than moving to Washington, D.C. right away.

A spokesperson for the Trump's noted that there is "obviously a sensitivity to pulling out a 10-year-old in the middle of the school year."

Barron attends Columbia Grammar and Preparatory School, located in the Upper West Side of Manhattan.

The elite school runs students about $47,000 a year.

With an eye on first kids who were teenagers or young adults when their parents lived in the White House, as far back as President Richard Nixon, Business Insider took a look at elementary, middle, or high schools they attended.

Take a look below to see who attended prep schools in the nation's capitol, and who went elsewhere.

Barron Trump — Columbia Grammar and Preparatory

If Barron's $47,000-a-year tuition payment seems steep, it's nothing compared to the cost of secret service protection in New York City for the first family, which is estimated to be $1 million a day.

Sasha Obama — Sidwell Friends School

Sasha is a sophomore at the Washington, D.C. based school that has educated multiple first kids. The Obamas have said they will stay in D.C. until Sasha graduates from high school. Sidwell costs students about $40,000 a year.

Malia Obama — Sidwell Friends School

Malia graduated from Sidwell in the spring, and announced she will be taking a gap year before starting college at Harvard University.

On the morning of December 16, 1944, more than 200,000 German troops and almost 1,000 tanks drove into the Ardennes, across an 85-mile stretch of the front line, running from southern Belgium to the middle of Luxembourg.

The German thrust shredded Allied lines, held by units sent to the Ardennes to rest and reorganize.

Bad weather held Allied air power in check, and many American troops were caught off guard. The US 106th Infantry division was encircled in hours, and two out of three soldiers were caught or killed. US forces settled into wholesale retreat, save for a few pockets of soldiers who fought on but were quickly isolated, though they held crucial road junctions.

The German offensive pushed a 50-mile bulge into the Allies' lines on the Western Front. Gen. Dwight Eisenhower saw a chance to break the German war machine, and more than a half-million troops were thrown into battle.

The two armies clashed in driving snow and sub-zero temperatures. Soldiers often couldn't see more than 10 or 20 yards in front of them. "Both the enemy and the weather could kill you," Private Bart Hagerman of the 17th Airborne said in a PBS documentary. "And the two of them together was a pretty deadly combination."

Casualities mounted for the US, and physical-fitness standards were lowered to pull in more troops. Men suffering from physical or mental wounds were thrown back into the fight.

"It's very hard to forget the expressions on their faces ... a kind of hollow-eyed, lifeless, slack-jawed expression," Ben Kimmelman, a captain in the 28th Infantry, said in the documentary. "It's almost as though they're going to a hopeless doom."

The battle lasted until the final days of January, when Allied troops returned to their original lines. Almost a million troops were engaged, and 16,000 Americans were killed with another 60,000 wounded or captured. German losses were thought to be twice that.

The marches were inspired by The Women's March on Washington, where nearly 200,000 people are expected to attend.

However, several other cities came out in strong numbers. Take a look at how the marches unfolded in nearly a dozen countries around the globe. 

UNITED STATES: The rally in Washington, DC, which inspired hundreds of "sister marches," got off to a strong start at Capitol Hill.

GERMANY: People gathered beside Brandenburg Gate in Berlin, holding "Love trumps hate" signs.

INDIA: New Delhi picked up the hashtag #IWillGoOut for its rally.

One of the most pervasive career trends today is the art of the side hustle.

Discovering a way to monetize your passions or hobbies, whether it be photography, writing, knitting, consulting, you name it, is a fulfilling way to earn some extra cash. Sometimes though, it becomes lucrative enough to pursue full time.

That was the case for 31-year-old Sara Barrett. After graduating from the Massachusetts College of Art and Design in 2007 with a degree in graphic design, Barrett started doing freelance work, creating wedding and baby shower invitations.

In 2009, a client suggested she list some of her artwork on Etsy, an online marketplace for creative sellers and buyers, she told Business Insider. She thought, "'What have I got to lose?'" and set up shop as SimkaSol.

After Etsy customers began requesting her paper prints on pillowcases and clothing, Barrett taught herself to screen print "by the grace of the internet."

"I started learning how to pattern draft and how to use all my industrial sewing machines and it's kind of just been this continual chain of learning a new trade and applying it and then learning another step, just constantly chugging forward," she said.

Barrett kept up with the freelance graphic design — as well as teaching horseback riding lessons — until she realized how lucrative her Etsy shop had become. "It really wasn't until late 2011 where I was like, 'Wow, I'm making enough money to pay all my bills and invest back into the business. So at that point I was like, 'I'm going to go for it," she said. Today, SimkaSol remains Barrett's main source of income.

To date, SimkaSol has raked in more than 16,000 sales on Etsy — and more than 47,800 "admirers"— which accounts for about 80% of Barrett's overall business, she said. The other 20% comes from selling a full collection of women's and men's clothing and home decor on her personal website.

Five years in and Barrett is still the sole employee of her company — aside from a little help from her friends during the holiday season. Business Insider recently caught up with Barrett at her in-home production studio in Massachusetts, where she walked us through a day of one of Etsy's most prolific sellers.

Barrett starts her day around 8 a.m. "When you work for yourself you can kind of be like, 'I'm going to get up when I want.'" After taking her dogs out for a walk, she fires up her coffee grinder, a gift from her parents that she's now "addicted" to. "It's probably the most important part of my day."

Barrett currently works out of her home, which includes a 300-square-foot studio. As a one-woman show, all the designing, marketing, and production rests on her shoulders. "I usually spend about an hour in the morning waking myself up to the business by checking emails, checking the site, looking at some statistics — views, likes, shares — just to see where I'm at," she said.

From there, she packages up any pending orders. "During the holiday crunch times, I can work all through the night," she says. "But when it's just my usual schedule I like to package through the morning because it gets me started on my day."

In 2015, I drove one of my kids to camp in a BMW i3, an extended-range electric vehicle that at the time was rumored to be a basis for the Apple Car.

The trip went great, so I decided to make our annual camp sojourn to the scenic Catskills in upstate New York a regular EV-paloooza. And what better car to serve as our futuristic chariot in 2016 than ... the Tesla Model S?

And not just any Model S, but a P90D with Ludicrous Mode: the baddest, fastest, coolest Tesla in all the land. (At least until the P100D arrived in early 2017.)

The idea was to see if this four-door luxury "family car" with supercar-beating acceleration — 0-60 mph in 2.8 seconds, claimed — could handle a journey of decent length (about 240 miles round trip) involving two adults, three kids, and the gear of a pair of campers for two weeks.

Quite a test, eh? And with a few scheduled stops to dine, take in the sights — and recharge the battery.

Our adventure began on a pleasant Sunday in July, just like 2015, and all initially went according to plan

Until it didn't.

Read on to learn all about our most excellent misadventure with the world's most famous electric car.

The pearl white Tesla, equipped with everything, landed in the driveway of our suburban New Jersey test car HQ.

My Prius was intimidated.

Our Tesla was the Model S sedan ...

Ralph Lauren has a long history of working with important American figures. The designer's most recent credits include dressing first lady Melania Trump for the 2017 inauguration.

Trump wore a powder blue Ralph Lauren suit, which many compared to the pale blue suit that Jackie Kennedy wore to her husband's inauguration in 1961. Ralph Lauren also designed the cream-colored suit that Hillary Clinton donned for the 2017 inauguration. 

Ralph Lauren is a name synonymous with American fashion. His net worth is now estimated to be nearly $6 billion, according to Forbes. And yet, the story of how he built one of the largest fashion companies in the world from nothing isn't quite so well-known.

Here's how he amassed that wealth, and what he uses it for.

Ralph Lifshitz was born in New York City in 1939, the youngest of four by Russian Jewish immigrants. As a teenager, he changed his last name to Lauren and walked around his Bronx neighborhood wearing outlandish styles like army fatigues and tweed jackets.

By 26, he was designing and selling his own neckwear. He put together "rags" and fashioned them into ties. He designed a fatter, European-style neck tie, making them "out of a drawer" in the Empire State Building.

Check out 33 of the best examples of Brady's competitiveness below.

It started in high school for Brady. He used to have his high school teammates over his house to study film while his mom made them lunch.

Americans are in over their heads when it comes to credit card debt.

The average indebted credit card holder carries an outstanding balance of $5,849, according to WalletHub. Collectively, Americans owed $927.1 billion on credit cards as of the third quarter of 2016.

In a recent study, WalletHub examined the relationship between a city's average credit card balance and its median income, ranking them by how long it would take the average person to pay off the debt given those factors. 

Cities where residents have high credit card balances and low median incomes (well below the national median income of $32,261) naturally fare the worst. Residents of these cities would likely struggle to meet the minimum payments on their high card balances, incurring hefty interest payments and potential fees and severely prolonging their repayment period.

Using WalletHub's data for the 25 worst cities, we determined the debt-to-income ratio for each city and ranked them based on this metric. That is, we ranked them based on the average resident's credit card debt represented as a percentage of the median income.

Below, check out 25 of the worst cities for credit card debt.
