The master’s degree in business administration (MBA) is one of the traditional education choices for people seeking high-powered careers with a lot of earning potential.

But MBAs aren’t cheap. A year of tuition at a top business school can easily exceed $50,000, and many programs last for two years.

Given that students are highly likely to have education debt from their undergraduate degrees, graduates’ student loan debt can easily reach six figures.

That can create a lot of pressure to find a lucrative job, because that pricey MBA probably won’t seem as valuable if you can’t afford your student loans, fall behind on payments and damage your credit.

(Keep in mind, there are income-driven repayment plans that federal student loan borrowers could use to help make loan payments more manageable. You can see how your student loans may be affecting your credit score by viewing your free credit report summary, updated each month, on Credit.com. )

Still, not every MBA requires you take on an obscene amount of debt. In-state tuition is probably the most common way to get a great degree for the least amount of money, though some private and out-of-state schools are still much cheaper than, say, Columbia University, which costs $65,988 per year.

Using U.S. News & World Report’s MBA rankings, we rounded up the top MBA programs you can attend for less than $15,000 in tuition each year (full-time).

If you think interview questions like "What's your biggest strength?" and "Where do you see yourself in five years?" are tough, you're in for a rude awakening. 

Some companies are asking far more challenging — an in many cases, oddball — questions of job candidates, like "How many basketballs would fit in this room?" and "How would you sell hot chocolate in Florida?"

Job site Glassdoor recently combed through its tens of thousands of interview questions shared by job candidates during the past year to find some of the most difficult and bizarre questions. 

"Job candidates at employers across all industries should be ready to answer any question, from the most basic to the most challenging," says Susan Underwood, Glassdoor's head of global recruiting and talent acquisition. "Employers are asking tough interview questions to test a job candidate's critical thinking skills, see how they problem solve on the spot, and gauge how they approach difficult situations. Employers want to determine how different candidates respond to challenges, and those who respond well may have the edge when it comes to receiving a job offer."

Interestingly, Glassdoor found that there is a statistical link between a tough interview process and greater employee satisfaction. Across six countries, more challenging interviews upfront were associated with higher employee satisfaction later on. 

Here are some of the strangest and most challenging questions companies are asking job candidates right now, according to Glassdoor:

In 2012, Mathematician Ian Stewart came out with an excellent and deeply researched book titled "In Pursuit of the Unknown: 17 Equations That Changed the World."

His book takes a look at the most pivotal equations of all time, and puts them in a human, rather than technical context.

"Equations definitely can be dull, and they can seem complicated, but that’s because they are often presented in a dull and complicated way," Stewart told Business Insider. "I have an advantage over school math teachers: I'm not trying to show you how to do the sums yourself."

He explained that anyone can "appreciate the beauty and importance of equations without knowing how to solve them ... The intention is to locate them in their cultural and human context, and pull back the veil on their hidden effects on history."

Stewart continued that "equations are a vital part of our culture. The stories behind them — the people who discovered or invented them and the periods in which they lived — are fascinating."

Here are 17 equations that have changed the world:

The Pythagorean Theorem

What does it mean? The square of the hypotenuse of a right triangle is equal to the sum of the squares of its legs.

History: Though attributed to Pythagoras, it is not certain that he was the first person to prove it. The first clear proof came from Euclid, and it is possible the concept was known 1,000 years before Pythoragas by the Babylonians.  

Importance: The equation is at the core of much of geometry, links it with algebra, and is the foundation of trigonometry. Without it, accurate surveying, mapmaking, and navigation would be impossible.

In terms of pure math, the Pythagorean Theorem defines normal, Euclidean plane geometry. For example, a right triangle drawn on the surface of a sphere like the Earth doesn't necessarily satisfy the theorem.

Modern use: Triangulation is used to this day to pinpoint relative location for GPS navigation. 

Source: In Pursuit of the Unknown: 17 Equations That Changed the World

The logarithm and its identities

What does it mean? You can multiply numbers by adding related numbers. 

History: The initial concept was discovered by the Scottish Laird John Napier of Merchiston in an effort to make the multiplication of large numbers, then incredibly tedious and time consuming, easier and faster. It was later refined by Henry Briggs to make reference tables easier to calculate and more useful. 

Importance: Logarithms were revolutionary, making calculation faster and more accurate for engineers and astronomers. That's less important with the advent of computers, but they're still an essential to scientists. 

Modern use: Logarithms, and the related exponential functions, are used to model everything from compound interest to biological growth to radioactive decay.

Source: In Pursuit of the Unknown: 17 Equations That Changed the World   

Calculus

What does it mean? Allows the calculation of an instantaneous rate of change. 

History: Calculus as we currently know it was described around the same time in the late 17th century by Isaac Newton and Gottfried Leibniz. There was a lengthy debate over plagiarism and priority which may never be resolved. We use the leaps of logic and parts of the notation of both men today.

Importance: According to Stewart, "More than any other mathematical technique, it has created the modern world." Calculus is essential in our understanding of how to measure solids, curves, and areas. It is the foundation of many natural laws, and the source of differential equations. 

Modern use: Any mathematical problem where an optimal solution is required. Essential to medicine, economics, physics, engineering, and computer science.

The Lexus RX has been around for so long that it's easy to forget how significant a vehicle it was when it hit the scene way back in 1998.

Up to that point, SUVs had essentially been upscale trucks. Lexus' parent company, Toyota, realized that many people, especially in America, were buying rugged four-wheel-drive SUVs when all they really wanted was SUV scale and utility. Their SUVs never got a whiff of trail; the closest they came to off-roading was when the parking lot of the Short Hills Mall needed a repaving.

Enter the RX, the first in a new breed of "crossover" SUVs, built not on truck platforms, but on more car-like undergirdings.

The RX was an immediate hit and has remained so for decades. Lexus has sold over 2 million of the RX 350, making it by far the most important vehicle in the luxury brand's portfolio. This is not a car that Lexus can afford to screw up.

That said, Lexus did revamp the RX, rolling out the new crossover at the New York Auto Show last year. The fourth-generation crossover is just as versatile as it's always been, but the design is newly aggressive, notably up front.

I live in the suburbs of New Jersey. This is the heart of the heart of RX country. Lexus loaned us a $60,000 RX 350 F Sport version, with all-wheel drive, and we tooled around in it around for a week. (A front-wheel-drive RX 350 is available, as is a hybrid RX 450.) Here's the lowdown:

Photos by Hollis Johnson

Let's just get right down to it. The so-called spindle grille is completely polarizing. You love it, you hate, but you don't hold back your opinion. Frankly, I think it's hideous, but the RX 350 had always struggled with the impression that it was bland, so I can see why Lexus went bold. And the grille design does look better at SUV scale than it does on Lexus' cars.

In profile, the RX 350 is quite sleek, with the caged energy of a silvery panther. But the pseudo-haunches over both the front and rear wheels look weird, as does the odd "floating" roof.

There is just a hot mess of folded metal that fills the field of vision when you consider the RX 350 from an angle. Swoop! Slash! Curve! Eek!

When you go in for a job interview, it's imperative that you make a stellar first (and lasting) impression.

But you can't rely solely on your impressive answers to get the job. You need to behave professionally, too.

As it turns out, there are tons of small mistakes you can make that could end up costing you the job.

To help you figure out what you should and shouldn't do during the job interview, we looked at responses to the question, "Employers of Reddit, what is a prejudice you hold against the people you interview?" which was recently posted on Reddit by okmann98.

Here's what respondents came up with:

DON'T MISS: The 27 jobs that are most damaging to your health

1. Guilt tripping the employer into giving you a job

"Telling me about how badly you need this job because of all the problems you have will get your application thrown in the trash," says Reddit user pinkiepieisbestpony, because candidates who have a lot of "baggage" usually turn out to be problem employees. 

Fellow commenter WhizmoAlke agrees and says they had someone actually cry during an interview. While it made them feel awkward, they say they were no more inclined to give them the job.

SoundBearier put it more bluntly: "This is a business, not the Red Cross." 

2. Graduating late with no work experience on your résumé

Reddit user creaoiumm — a lawyer — says they are tired of seeing applications from law-school students who are over 26 years old and have no job experience (not even babysitting!).

Instead, he says their résumés tend to be filled with different hobbies or trips they took during the summer. "As someone who started working at age 16, I'll admit I think less of someone in their late 20s who has never held any kind of job, however small."

3. Having your parents inquire about jobs on your behalf

ScarinasVault — a middleman between candidates and HR — says they've seen a marked increase in the number of parents asking for jobs on behalf of their kids or even asking for help with their child's résumé. 

While these actions may come from a good place, the commenter says, "if you can't bother to show up to ask then we can't be bothered to take you seriously." 

Getting a good night's rest is about more than just going to bed at an appropriate time.

It's also about arranging your evening so that it's not stressful or stimulating in a way that can make it hard to fall and stay asleep.

We know: It's easier said than done.

To help you out, we've rounded up seven common behaviors that can ruin your rest — plus what you can do instead.

SEE ALSO: 7 things not to do when you first wake up

1. Don't use any kind of digital technology.

A growing body of research suggests that staring at the blue and white light emitted from digital screens prevents your brain from releasing the hormone melatonin, which lets your body know when it's time to hit the hay. So it becomes harder to fall and stay asleep.

Take a tip from Arianna Huffington, cofounder and editor of The Huffington Post, who’s banned electronics from the bedroom and reads a hard copy book before going to sleep.

2. Don't take sleeping pills (unless you've been diagnosed with insomnia).

The Centers for Disease Control and Prevention estimated that, during a single month in 2013, 4% of Americans over age 20 used a prescription sleep aid.

But as Harvard sleep scientist Patrick Fuller told Tech Insider's Julia Calderone, "I think most people that are taking hypnotic medications actually don't need them and should work to get off of them."

According to Fuller, even if you have trouble sleeping, you probably don't have insomnia, and taking sleeping pills probably won't do you much good.

The medications typically come with a host of side effects, from muscle aches to memory loss. Plus, Fuller said, they can be highly addictive, and your sleeping problems may become worse after you take the pills.

3. Don't drink alcohol.

As anyone who's nodded off after a few glasses of wine is well aware, alcohol often helps you fall asleep.

But research suggests that it can make it harder to stay asleep. As your body starts to metabolize the alcohol during the second half of the night, you may start to get restless.

As Tech Insider's Julia Calderone reported, studies have found that drinking before bed suppresses your rapid eye movement (REM) sleep in particular, which is important for memory and concentration.

Your home is likely full of items you’re no longer using, and some of them could be worth hundreds or even thousands of dollars.

“Whether it’s personal items or family heirlooms that have been passed down for generations, many people underestimate the value of the possessions collecting dust in storage,” said Jacquie Denny, founder of Everything But The House (EBTH), an online estate sale service.

In particular, buyers are willing to pay top dollar for anything rare or in limited supply, Denny said. However, even everyday items can bring in extra cash. As the saying goes: "One man’s trash is another man’s treasure."

If you need extra money, check out these 20 sources of hidden income that could be lying around your house.

1. Clothing

Chances are that you and your loved ones have clothing that’s collecting dust in a closet. If these items are gently worn, you might be able to cash in by selling them. One of the easiest ways to unload your used clothing for cash is to sell items on consignment.

I’ve been selling clothes through a local consignment store for years and regularly receive 50 percent of the selling price for items I unload. To earn top dollar, look for upscale consignment stores that enjoy a lot of foot traffic. Additionally, you should find out what brands and items the store accepts and make sure your clothing meets the store’s standards.

You can also sell to an online reseller such as Thredup.com, which will send you a pre-paid package to ship your items. Thredup sellers can earn up to 80 percent of the marked price of their items.

2. Designer shoes and handbags

If you paid big bucks for designer shoes or a handbag that you now rarely use, you can reclaim some of your money by selling these items online. Frugal living expert Lauren Greutman, who blogs at IAmThatLady.com, said she has sold shoes through Poshmark for up to 50 percent of the retail price.

You can snap a picture of the items you want to sell using the Poshmark app and list them instantly. Poshmark will send a pre-paid box to ship items that sell and take a $2.95 commission for sales less than $15 and a 20 percent commission for sales above $15.

3. Jewelry

If you have an inherited necklace that isn't your style, or an engagement ring you no longer wear because you're divorced, you might want to consider selling these pieces for cash. Said Denny, fine jewelry can be worth a lot.

To make sure you get the full value of your jewelry, consider having items appraised beforehand. You can find an appraiser near you through the American Society of Appraisers' site, Appraisers.org, or sell online through an auction site such as eBay.com. While you can also opt to sell to a jeweler or pawn shop, it's important to seek out quotes from several stores before doing so.

A company that made its name — and a $16 billion valuation — by renting out shared workspaces now wants to do the same thing with dorm-like apartments.

In WeWork's biggest gamble yet, its co-living micro-apartment space, WeLive, officially opened its doors to New York residents on Monday.

Individual Murphy beds that pull down into the living room behind a curtain or tiny alcoves in a wall start at $1,375 a month. If you want more privacy, rooms start at $2,000. The high price tag — and a $125 amenities fee — helps support "all the coffee, tea, and beer you can drink," according to the WeLive website.

Each apartment or bed comes fully loaded with towels and linens. There's also a full-time "community concierge" and a housekeeping team. The laundry room has a ping-pong table and billiards, and a wellness room hosts yoga and barre classes. The fridge comes fully stocked with Smart Water, S.Pellegrino, and beer.

No one ever said that city living was cheap, but WeWork is betting that its WeLive spaces will be the start of a new movement. They're perfect landing pads for people moving to a city looking for instant friends and not having any furniture. Whether those people stay — and become WeWork members — will be the crucial litmus test.

If turnover is too high, it could start feeling more like a hotel and less like a communal neighborhood of friends all with really tiny bedrooms. The month-to-month leases are great flexibility for its residents, but could be hard on WeWork's bottom line if it can't fill the Murphy beds fast enough.

Currently the company has two locations: one in New York and one in Crystal City, Virginia, near Washington DC. The Crystal City location is slightly cheaper, with beds starting at $1,000 and private rooms beginning at $1,300, but it won't officially launch until May 1.

WeLive's average apartment size is 450 square feet. This studio starts at $2,000 a month.

Each apartment comes fully stocked with the basics for your kitchen.

Everything is fully furnished, down to the sheets on the bed, too. WeLive's vibe ends up looking like an upscale IKEA.

Critics agree that the striking imagery of the battle against Doomsday in "Batman v Superman" was one of the best parts of the film.

Victoria's Secret has figured out how to turn lingerie into a $6 billion business.

A huge reason for the company's success is its very successful marketing strategy. It's known for being the beacon of all things sexy.

But sexiness was depicted differently when Victoria's Secret was born in 1977 when it was founded by Roy Raymond.

Here's how the brand has changed — in photos.

SEE ALSO: Victoria's Secret has a strategy for casting models that's worth $6 billion

Then: Victoria's Secret actually resembled a boudoir.

"Raymond imagined a Victorian boudoir, replete with dark wood, oriental rugs, and silk drapery. He chose the name 'Victoria' to evoke the propriety and respectability associated with the Victorian era; outwardly refined, Victoria's 'secrets' were hidden beneath. In 1977, with $80,000 of savings and loans from family, Raymond and his wife leased a space in a small shopping mall in Palo Alto, Calif., and Victoria's Secret was born," Naomi Barr wrote on Slate.

Now: Hints of its past are occasionally present in its Facebook photos.

Then: You would have been able to find this sort of image in a Victoria's Secret ad.

The overtly provocative nature of Raymond's Victoria's Secret was slightly altered when Les Wexner took the helm of the brand — but make no mistake, lingerie still abounded.

We know: Reading about retirement can sometimes make you feel like you are staring into a bowl of alphabet soup.

So while you know that you need to start building a nest egg, the financial jargon involved can make it seem like a challenging and confusing task — so you keep putting it off until you can "do more research."

Either that, or you're hoping there's a windfall in your future: According to a 2015 study by the Insured Retirement Institute and the Center for Generational Kinetics, more than a quarter of Millennials are banking on either winning the lottery or receiving an inheritance as their retirement strategy. (Spoiler alert: This probably isn't your best-laid plan.)

So unless you just hit the jackpot, today is as good a time as any to start socking away for retirement. And to make the task less of a mystery, we've compiled seven of the most common terms you're likely to see scattered throughout the paperwork from your HR department or financial services provider.

Once you've brushed up on the basic lingo, you can get started on building your retirement plan, stat.

1. Defined benefit plan

An employer-sponsored retirement plan in which your company would pay a regular benefit to you after you retire. This benefit could either be a specified monthly dollar amount or a figure based on a calculation that incorporates factors like your earnings history and years of service. The money typically comes from a pool of funds that is invested by the company on behalf of its employees.

If your company offers this kind of plan, you may or may not be asked to contribute to it, although typically, you won't. One of the most common types of defined benefit plans is a pension — however, fewer and fewer companies these days offer one, which means pensions are slowly going the way of the dodo. So more likely than not, the retirement plan offered by your new company will be a …

2. Defined contribution plan

Consider this the more DIY version of the employer-sponsored retirement plan. In this type you contribute funds into a retirement account set up for you by your employer, who may also make a contribution on your behalf.

However, unlike with a pension, you choose how you'd like to invest your money, based on the options offered by your plan provider. That means how much you end up with in retirement depends on you: how much you choose to contribute as well as what type of return your investments ultimately provide.

RELATED: Your 401(k): When It Was Invented — and Why

3. 401(k)

A 401(k) is one of the most popular types of defined contribution plans, and there are two different kinds that may be offered to you by your company.

A traditional 401(k) allows you to contribute pretax dollars from your paycheck. This means that what you contribute now helps lower your taxable income, and any earnings in your account are tax-deferred — i.e., you won't pay taxes on them until you withdraw your funds in the future.

A Roth 401(k) allows you to contribute on an after-tax basis. That means you pay taxes upfront on your contributions — but you don't pay taxes on that money or any earnings when you make withdrawals in retirement.

Before you go gangbusters on your nest-egg building mission, however, know that there is a maximum amount you can contribute to your 401(k) each year. For 2016, employees under 50 years old can contribute up to $18,000, whether you have a traditional, Roth or a combination of both. Because they are closer to retirement, employees 50-plus can also make additional "catch-up contributions" of up to $6,000, for a maximum contribution of $24,000.

(By the way, if you work for a university, the government or a nonprofit, your version of the 401(k) is likely to be called the 403(b) or 457 plan.)

It seems as though we can pay people to do anything for us these days: walk our dogs, build our furniture, organize our homes ... cuddle with us when we're feeling lonely.

That's right: You care hire a professional cuddler to snuggle with you for about $60 an hour. You can also pay an "undercover bridesmaid" to stand next to you on your big day, or a professional mourner to cry with you at a loved one's funeral.

Those are just a few of the weirdest jobs we found while compiling our list of the most unusual professionals.

Millennials came of age during a tough economic time: Student debt has reached an all-time high, and the job market is more competitive than ever. As a result, young people today aren't earning as much money as their parents did when they were young. So how much are they making?

Using data from the Minnesota Population Center's 2014 "American Community Survey" in the Integrated Public Use Microdata Series, we found the median annual total personal income for employed millennials. We used the Pew Research Center's definition of millennials: Americans born between 1981 and 1997.

The medians ranged between a low of $18,000 per year in Montana and a high of $43,000 in the District of Columbia. How do you stack up?

Note that the youngest millennials are college-aged and may only be working part-time, which may skew the median downwards.

Below, we included the median annual personal income by state for all employees over age 17, also from the Minnesota Population Center's 2014 "American Community Survey" in the Integrated Public Use Microdata Series.

After using your 20s to find yourself, your 30s are typically a time for further establishing your career and personal life.

Many 30-somethings are busy rising through their work hierarchy, developing a serious romantic relationship, and possibly raising a family.

Those who have already been through that decade say that as their responsibilities accumulated, it became easier to neglect relationships and ignore opportunities that they would never get again.

We've sorted through a variety of advice from writers on Quora and author Mark Manson's blog and found recurring themes.

Here are eight things successful people don't do in their 30s.

SEE ALSO: 15 things successful people don't do in their 20s

They don't lack purpose.

It's common for undergraduate college students lacking specific career goals to pick a relatively safe, well-tread path with the hope that things work out. At some point in their 30s, some of these same people may have multiple degrees and wealth, but realize that they are deriving no meaning from their careers.

This happened to designer Jack Sheu when he was 35. "I learned that if you don't have your purpose, then make it your obsession in life to find it," he writes on Quora. "It took me over a year, and I was completely disconnected from the rat race during that time. Don't stop until you've got it. You'll know when you have."

They don't neglect a financial foundation for the future.

If you developed a spending habit in your 20s at the expense of saving for your future, it's not too late.

An anonymous poster writes on Quora that when his salary increased dramatically, he started spending excessively on things like expensive cars, a motorcycle, and a boat. Only in retrospect did he realize the danger of burning through money.

"Had I invested the money instead, I could have comfortably retired now (I am 44)," he writes.

They don't obsess about the future.

Manson recounts that one of the biggest lessons of his 20s was that there's not a magical moment where you start feeling like an adult who has it all figured out. He was happy to learn that his older readers said the same thing about their 30s.

"Unless you are already dead — mentally, emotionally, and socially — you cannot anticipate your life five years into the future. It will not develop as you expect. So just stop it. Stop assuming you can plan far ahead, stop obsessing about what is happening right now because it will change anyway, and get over the control issue about your life's direction,"Thomas, a reader of Manson's blog, writes.

It's healthy to have goals for you and your family, but don't stress out over specifics. Acknowledge that you still have plenty left to learn and that you're going to continue to grow as a person in unexpected ways.

KFC is making some major changes after losing customers' trust.

With a new "Re-Colonelization" program, employees are being retrained on how to correctly prepare KFC chicken.

"Customers were saying, 'Your food doesn't taste the same,'" Jason Marker, KFC's US president, said on Monday in a press event. "We're not making the food the same way the Colonel had, and we're not making food in what he described as 'the hard way.' Today marks the end of that."

At the event, KFC head chef Bob Das and comedian Rachel Dratch — continuing KFC's commitment to employing former "Saturday Night Live" cast members — gave a step-by-step look at how KFC chicken is made.

SEE ALSO: KFC is fixing a mistake it has been making for years

Step 1: Prepare the breading mixture, which includes flour, salt, milk, egg powder, and all of the Colonel's original secret seasoning. According to Das, even he doesn't know what spices are in the original recipe.

To ensure a proper distribution of the dry breading mix, KFC employees are instructed to "twist and fold" the dry ingredients 20 times, then sift the mixture.

Step 2: Dump out the chicken and inspect for defects. For example, any chicken that has part of a bone broken off or that looks bruised in some way would be discarded.

The name was inspired by the Cinerama, a wraparound movie theater format from which the boat takes it elegantly curved windscreen. It was an instant hit among the newly wealthy of the jet-set era.

Ferruccio Lamborghini was a customer— he had his refitted with two V12 engines from his 350 GT road car.

The auction house has not released an official sale estimate for the boat yet, but here is a list of similar Aquarama Specials on Yachtworld, all for north of $600,000.

Here's a look at the boat for sale in Monaco.

Two keys for two engines. Carlo Riva was noted for an obsession with quality, which is evident in the many, many details — just look at that leather steering wheel!

Aging infrastructure and booming demand for air travel have put a sometimes unbearable strain on North America's airports. While it's no secret our domestic facilities often lack the amenities and architectural flair of their international counterparts, there are a few that can more than hold their own.

Leading aviation reviewer Skytrax just released the results of its annual World Airport Awards, which includes a list of the best airports in North America. The Skytrax annual rankings are based on the impressions of over 13 million fliers from 106 countries. More than 550 airports were included in the survey, which covers 39 service and performance parameters, including facility comfort, location of bathrooms, and the language skills of the staff.

10. Halifax Stanfield International Airport (YHZ)

Yearly passengers: 3.7 million

Previous rank: 8

Why it's great: Stanfield is the smallest airport on this list, but it's not without its charms. Skytrax named Stanfield the fourth-best regional airport in the North America in 2016. Customer reviewers raved about the regional cuisine served at the airport, which includes fresh lobster.

9. New York John F. Kennedy International Airport (JFK)

Yearly passengers: 56.8 Million

Previous rank: 9

Why it's great: For many, JFK Airport is synonymous with the glory years of aviation. For others, JFK is no more than a crumbling relic of a bygone era.

In reality, the JFK of today is neither. Gone are the dated 1960s-era terminal buildings and their dilapidated facilities. In their place are modern terminal facilities that are either newly constructed or recently renovated. JFK customers cite the airport's new terminals and shorter security lines as key improvements.

8. Dallas/Forth Worth International Airport (DFW)

Yearly passengers: 64 million

Previous rank: 10

Why it's great: DFW is the fourth-busiest airport in North America and the ninth busiest in the world. The airport serves as the main hub for American Airlines, as well as the gateway to Latin America for many others. Customer reviewers liked the airport's open circular design and convenient intra-airport transportation.

The Hydraulic Press Channel is amassing millions of views on YouTube by giving the people what they want: videos of a bunch of stuff getting crushed.

They've smashed a golf ball, a Barbie, and enough fruit to make a very smooshed salad.

General Electric's engineers have smashed some everyday objects, too, using their micro forge at the Global Research Center in Schenectady, New York.

The micro forge can heat up to the temperature of an active volcano and compress objects with 100,000 lbs. of pressure.

We've put together a ton of GIFs from Hydraulic Press Channel and GE videos so you can get in on the action, too. It's pretty amazing to watch what cracks under pressure — and what survives.

Barbie is flexible, but not flexible enough to withstand the Hydraulic Press Channel on YouTube.

Silicon Valley has a huge diversity problem.

According to reports released by the largest tech companies last year, the stats are pretty dismal. Women hold only 18% of Google's tech jobs. Only 1% of Twitter employees are Black. At Facebook, barely 3% of workers are Hispanic.

Helena Price, a photographer who lives in San Francisco, captured this underrepresented slice of Silicon Valley. For her new project called "Techies," she interviewed and took 100 portraits of coders, designers, and CEOs who work in tech and come from diverse backgrounds.

Launching today, it features an eclectic mix: women, people of color, immigrants, people without formal education, people over 5o, LGBTQ people, and the disabled.

She hopes to challenge stereotypes of those working in tech and encourage tech companies to hire and retain a more diverse workforce. All of the portraits are fair use.

"I created this with the hope people will take the content, digest it, tear it apart, analyze it, repurpose it, and build new things with it," Price tells Tech Insider.

Take a look at the featured workers, including folks from Facebook, Google, and Apple.

Price posted a call for subjects in January and received over 500 applicants in a matter of days. After she narrowed the pool down to 100, she interviewed the subjects about their experiences working in Silicon Valley.

Then, over the course of March, she took their portraits.

Many of her subjects reiterated similar sentiments, like the fact that a sense of belonging is tough when no one else looks like you. "I have only met one other black female designer in tech in the past six years," Tiffany Taylor, a self-taught web designer, told Price.

As a financial planner who specializes in working with Gen X and Gen Y clients, I’ve come to learn a few basic facts about money.

I'll share those with you today in hopes that it provides you some insight to what, from a professional standpoint, you can do to be smarter with your money.

Pay yourself first.

This is a really important concept. When you get a paycheck, you save a portion of that money before you even pay your bills. You make this automatic, and you can set up automatic payments either through HR or bank drafts. Money is automatically being saved for all of your various financial goals — and that’s what it means to pay yourself first.

Focus on your income.

Too often we get caught just looking at the expense side of things and how much you can cut out of your budget. We preach about spending less and saving more. But we don’t look at how much more money we can earn.

Whether that be through salary negotiations at work, through a side hustle, or even through handyman work on the side, it’s important to find ways to focus on your income, too. How can you increase your earnings? What actions can you take to earn additional money?

It’s a lot easier, in my opinion, to find ways to make an extra $500 a month than to cut your monthly spending by $500 a month.

Invest in yourself before saving for retirement.

The number one rate of return that you will ever get on an investment is going to be through investing in yourself. What this means is getting additional certifications or designations, going back to school, getting additional expertise, or whatever that is for you and your career path that can help you earn more money.

That's going to give you significantly higher ROI long-term because it’s going to increase your income more than it would to simply sock money away for retirement. Now that’s not to say it’s not important to save for retirement, but if you're forced to choose between the two — especially as a young individual — invest in yourself.
