Sometimes, spending a little more is totally worth it.

But how do you know which indulgences are worth it? Or whether you're actually paying for quality, rather than just hype?

We combed through Reddit and Quora to find out which expensive purchases users had no regrets about making.

With Ferrari's upcoming IPO in October, fans of the prancing horse will finally be able to own a piece of the Italian automaker without forking over hundreds of thousands of dollars. 

But for many, there's no substitute to the raw power and emotion of a living, breathing Ferrari. Since the company launched its road car business in 1947, it's reputation has grown from that of a respected racing team to a creator of automotive legends. 

In fact, the company has managed to maintain a waiting list for many of its models without engaging in any forms of traditional advertising. 

Other the years, Ferrari has been responsible for a long line of fast, powerful, and evocative sports cars and supercars. Anyone who has ever encountered a Ferrari has his or her personal favorite. Which is why Business Insider compiled a list of the 10 best Ferraris in the world.

166 Inter: Built from 1948 to 1950, the Ferrari 166 Inter was based on the company's successful 166 race cars. The model was Ferrari's first international sales success.

The 166 was powered by a 2.0-liter, 90-horsepower V12 engine.

250 TR Testarossa: The 1957 250 TR was one of the first Ferraris to carry the iconic Testarossa badge. Testarossa, or "red head," is a reference to the car's red painted engine head covers.

You don't need to be born in Silicon Valley to make it as a tech entrepreneur.

As this list proves, founders come from every corner of the U.S., and each state has someone who has changed the tech landscape.

Alabama: Jimmy Wales, co-founder of Wikipedia and Wikia, credits his upbringing in Huntsville, Alabama for his passion for education. Despite running the fifth most popular website in the world, his net worth is estimated to be slightly over $1 million.

Alaska: Larry Sanger, the other co-founder of Wikipedia and founder of Infobitt, moved to Anchorage when he was seven.

Arizona: Phoenician Joan Ganz Cooney changed television forever when she helped found the Children's Television Network, the creators of Sesame Street. Her career didn't stop in showtime, though. She founded the Joan Ganz Cooney Center, which specializes in increasing literacy through digital technology. The eponymous center has hosted things like the National STEM Video Game Challenge and launched a news site dedicated to reporting on educational gaming.

Melbourne, Australia is about to get a "flawless" new addition to its skyline.

Just approved by the city's planning commission, a skyscraper known as the Premier Tower is set to rise in the city's central business district. And you won't believe where its architects found their inspiration: a Beyoncé video. 

The media kit details the design's ability to "redistribute the building’s mass" before alluding to its aesthetic inspiration by saying, "We're going to trust you've seen the music video for Beyoncé's 'Ghost'?" 

We first learned about the tower from the Creator's Project, but it's making its way around the web on everything from design blogs to fashion websites, thanks to the Beyoncé correlation.

Savvy CEOs and executives know that interview questions like, "What's your biggest strength?" and, "What's your biggest weakness?" aren't as telling as they seem.

That's why they steer clear of these cliché queries and instead ask more meaningful ones.

Many top execs have their one favorite go-to question that reveals everything they need to know about a job candidate. Here are 23 of them.

This is an updated article originally written by Alison Griswold and Vivian Giang.

"What didn't you get a chance to include on your résumé?"

Billionaire Virgin Group founder Richard Branson explains in his book "The Virgin Way: Everything I Know About Leadership," that he isn't a fan of the traditional job interview, reports Business Insider's Richard Feloni.

"Obviously a good CV is important, but if you were going to hire by what they say about themselves on paper, you wouldn't need to waste time on an interview," Branson writes. That's why he likes to ask: What didn't you get a chance to include on your résumé?

"On a scale of one to 10, how weird are you?"

One of Zappos' core values is to "create fun and a little weirdness," Tony Hsieh, CEO of the company, told Business Insider in 2010.

To make sure he hires candidates with the right fit, Hsieh typically asks the question: "On a scale of one to 10, how weird are you?" He says the number isn't too important, but it's more about how people answer the question. Nonetheless, if "you're a one, you probably are a little bit too straight-laced for the Zappos culture," he said. "If you're a 10, you might be too psychotic for us."

"How would you describe yourself in one word?"

The best candidates are the ones who know exactly who they are. That's why Dara Richardson-Heron, CEO of women's organization YWCA, always asks her candidates this question.

Richardson-Heron has said she doesn't judge people on the word they choose, but it does give her insight into how people package themselves. She tells Adam Bryant at The New York Times that she likes when people take time to ponder the question and answer thoughtfully.

"Batman: Arkham Knight," as with every game in the "Arkham" series, is packed to the gills with Easter eggs and sly references to other characters and events in Batman's world. They're probably one of the best aspects of the series. 

Where "Arkham Knight" differs from the rest, however, is in the substance of all these nods and references. While previous games focused pretty squarely on the wider Batman mythos, "Knight" doubles down on the world beyond Batman, making lots of references to other DC superheroes and a few other supervillains. 

Of course, this isn't a comprehensive list — after all, the development studio Rocksteady Games once hid a secret so well in "Arkham Asylum" that it had to rat itself out years later — but it gives a good feel about how other heroes may fit into the world of the "Arkham" games. 

Some light spoilers ahead. 

There's a great nod to the Emmy-winning "Batman: The Animated Series."

"The Ghost in Gray" posters scattered around Gotham allude to the "Batman: The Animated Series" episode "Beware The Gray Ghost," in which it was revealed Bruce Wayne was inspired to become Batman by the fictional Gray Ghost (voiced by '60s Batman Adam West). Years later, the actor who portrayed Gray Ghost returns to the spotlight to team up with Batman and stop the Mad Bomber (voiced by "Batman: TAS" creator Bruce Timm). 

It's pretty meta. 

The origin of Clayface.

Clayface is a pretty important character in the "Arkham" games, with a fun cameo in "Arkham Asylum" before taking on a bigger role in "Arkham City."

This poster is before all that, though, when he was just a horror-movie actor in the classic film "The Terror." His path to villainy would begin when his studio would decide to remake "The Terror"— without him.

The Black Canary has a side gig.

If you watch "Arrow" or "The Flash" on the CW, you may know about the DC superhero Black Canary— she doesn't appear in "Arkham Knight," but this club is named after her — and it's apparently frequented by the poker-card-themed villains of the Royal Flush Gang. 

The 20 coolest beach towns in America are about drinks at sunset and living in flip-flops.

They’re about waking up with sand in your sheets and going to work barefoot.

Perfect days here are ones with the right wave, the right wind, or the right fish.

And the people who live here know the one thing they could never live without is the ocean.

We picked our twenty favorite beach towns based on the following criteria:

1. Small: No major cities allowed.

2. Year-round energy: The town can’t pack up and leave after “the season”.

3. Entertainment outside of the beach: Music, breweries, galleries, museums, and festivals also play integral parts of the culture.

Check them out below.

Fort Myers, Florida

There are more than enough reasons to love Fort Myers and Sanibel Island: great weather (the Gulf water averages 76 degrees, almost never dipping below 60 even in the wintertime), delicious food (it’s rumored that Jimmy Buffett wrote “Cheeseburger in Paradise” after dining at an area restaurant), fantastic outdoor sports. It has the best of Florida, without the over-development. It’s also been repeatedly voted as the #1 shelling beach in the nation by Travel + Leisure. 

Honor roll

Drinks: Peel ‘n eat shrimp and a cold beer at the Lazy Flamingo.

Eats:  Stop by Andy’s Island Seafood Mobile Truck. Also visit Sanibel Farmer’s Market and the Captiva General Store.

Coffee: Visit The Island Cow for a big breakfast or lunch. Try a slice of Key Lime Pie at the Key Lime Bistro.

Things to do: Visit Bowman’s Beach, one of the world’s best shelling beaches. Cheer on spring training baseball in Fort Myers. Visit the Edison & Ford Winter Estates Museum. Check out the the National Shell Museum and paddle in the JN “Ding” Darling National Wildlife Refuge. Explore the Matlacha Pass National Wildlife Refuge.

Stinson Beach, California

Looking for a beach town that embodies the slow life? You’ve found it. Stinson, a cherished staple of Nor Cal folks,   sits between the Pacific Ocean and Mt Tamalpais, an area with some of California’s best views and hikes through old growth redwood forests. The town’s main drag doesn’t have a single stop light and during the week, you might have the beach literally to yourself.

Honor roll

Drinks: Have a freezing cold Mirror Pond draft at Sand Dollar Restaurant.

Eats: Stop in for a gourmet meal at Parkside Cafe.

Coffee: Breakers Cafe.

Things to do: Visit Stinson Beach State Park and take any of the several hikes that stem from the beach.

Bar Harbor, Maine

Martha Stewart vacations in this artsy town that has access to Acadia National Park as well as some of Maine’s best sandy beaches.

Honor roll

Drinks: Cottage Street Pup has super interesting drinks, located in a hallway-sized space. Or, for an outdoor gazebo bar where the locals go, visit the Dog and Pony (they’re also the only place to get food late-night).

Eats: McKay’s Public House has a great lobster mac and cheese in a fabulous ambiance (a historical building with outdoor seating in the summertime, and fireplace tables during winter). The restaurant also has the town’s best local and international beer selection (they even have a cask-conditioned tap line). Ask for Chris ‘Rome’ Romero, their locally-famous bartender here; he knows all there is to know about beer and brews his own.

Cafes: Two Cats bakery has a huge outdoor covered porch and a really good breakfast burrito. Jordan Pond House is known for their homemade Maine blueberry jam. Cafe This Way also serves excellent bloody mary’s.

Things to do: Stay one night in the Acadia Yurts in nearby Southwest Harbor. Hike the peak of Cadillac Mountain, where the first sunrise in the United States is said to occur. Go whale watching. Visit the Abbe Museum for Native American artifacts from the region.

Rejection can feel genuinely devastating. But before you retreat into your tear-stained hovel to plot a new, anonymous life as a subsistence farmer in rural Australia (not that there's anything wrong with that!), consider this: Some of the world's most successful people have failed — sometimes more than once.

We've put together a list of indisputably successes, from movie stars to scientists, who experienced massive failure before they found fame and fortune.

Weaker people might have given up. Instead, these folks remained focused on their goals.

Walt Disney was fired from the Kansas City Star because his editor felt he "lacked imagination and had no good ideas."

Several more of his businesses failed before the premiere of his movie "Snow White." He went onto become the guy who redefined American childhood.

Oprah Winfrey was publicly fired from her first television job as an anchor in Baltimore for getting "too emotionally invested in her stories."

But Winfrey rebounded and became the undisputed queen of television talk shows before amassing a media empire. Today she is worth a cool $3 billion, according to Forbes.

Steven Spielberg was rejected by the University of Southern California School of Cinematic Arts multiple times.

He went on to create the first summer blockbuster with "Jaws" in 1975, has won three Academy Awards, 4 Emmys, 7 Daytime Emmys, and his 27 movies have grossed more than $9 billion.

All eyes were on the New York Stock Exchange on Wednesday after it halted trading for 3.5 hours due to a technical glitch.

The second "Batman v Superman: Dawn of Justice" trailer debuted at San Diego Comic-Con this weekend, and it was absolutely jam-packed. 

Clocking in at nearly three and a half minutes, the trailer gives us our first look at the plot of the film alongside a plethora of Easter eggs and glimpses at what the wider DC Universe will look like in the movie. 

Let's dive right in.

They're addressing one of fans' biggest issues with "Man of Steel."

A big problem a lot of fans had was the widespread destruction in the big finale to "Man of Steel." The movie sort of acted like it was no big deal. "Batman v Superman" looks like it's going to take this head on, revealing that Bruce Wayne was at the scene, and he's very, very angry. 

We finally know Batman's big problem with Superman.

Now that we know Bruce was in Metropolis when it was nearly leveled, we learn the personal stake he has in it — one of his buildings was completely destroyed in the fight, and Wayne feels responsible for the people who died on his watch.

This Batman is kind of messed up.

Ben Affleck's portrayal of Batman is the angry, ruthless sort with none of the deep sadness that seemed to haunt Christian Bale. He also seems to take things a bit too far — it looks like he even brands criminals he apprehends!

Hiring managers receive dozens — sometimes hundreds — of résumés for any given opening.

They don't have the time or resources to review each one closely, so they spend approximately six seconds on their initial "fit/no fit" decision. 

You may be perfect for the job, but if your résumé has just one typo, if it's formatted poorly, or you use the wrong font, it could easily end up in the "no" pile.

SEE ALSO: 9 steps for figuring out which skills to include on your résumé

1. An objective.

If you applied, it's already obvious you want the job.

The exception: If you're in a unique situation, such as changing industries completely, it may be useful to include a brief summary. 

2. Irrelevant work experiences.

Yes, you might have been the "king of making milkshakes" at the restaurant you worked for in high school. But unless you are planning on redeeming that title, it is time to get rid of all that clutter.

As Alyssa Gelbard, career expert and founder of career-consulting firm Résumé Strategists, points out, however, past work experience that might not appear to be directly relevant to the job at hand might show another dimension, depth, ability, or skill that actually is relevant or applicable.

Only include this experience if it really showcases additional skills that can translate to the position you're applying for.

3. Personal stuff.

Don't include your marital status, religious preference, or social security number.

This might have been the standard in the past, but all of this information is now illegal for your employer to ask from you; so there's no need to include it.

Of all the cities in the world, your dollar will go the furthest in Mumbai, India.

It's currently the cheapest city to live in, according to the Economist's World Cost of Living Index.

The index, which is calculated every other year, compares countries based on the cost of things like food, drink, clothing, rent, transportation, and utility bills.

It's designed to help companies figure out how much to compensate employees who are working overseas. 

Some of the world's cheapest cities, like fourth-ranked Damascus, Syria, are also among the most dangerous. This list shouldn't be considered a guide for people who are looking to save money by moving overseas — try this list of places where expats can live for cheap instead — but rather as a look into the cost of living in places far away from home.

All prices listed are from the Economist's World Cost of Living Index. Mandi Woodruff contributed to an earlier version of this article.

French artist JR works anonymously, but the giant images he pastes on buildings, streets, and bridges around the world are meant to put faces on often-ignored slices of society, from victims of crime to the elderly.

The "photograffeur"— that's a combination of photographer and graffiti artist — prints humongous versions of the portraits he takes, often in black and white, and "flyposts" them where he chooses. The exhibits span whole cities and continents.

JR, who has received a TED Prize for his work, sees the streets as his stage and says he "owns the biggest art gallery in the world."

Keep scrolling to see some of the artist's most visually arresting works.

In early 2014, JR took portraits of dozens of people, and turned them into a collage around the dome of the Pantheon in Paris while it was under construction. The installation depicted "the diversity of the contemporary world."

Ah, summer. The perfect time to get caught in an unexpected rain shower accompanied by lightning and thunder.

In the northern hemisphere, most lightning occurs in the summer months. (A word of warning: It's also the time of year when the most deaths by lightning occur.)

Here are some of the most epic images of lightning strikes that photographers have captured in recent years.

Lightning is created when positive and negative charges bump up against one another inside clouds and discharge their electricity. Ever pulled off a freshly-dried sweater and felt your skin crackle underneath? Same idea. In this photo of a lightning storm from last week outside Barstow, California, electricity charges the ground in lines of light.

Contrary to popular belief, lightning can strike the same place twice, especially tall buildings. People once thought a lightning strike permanently changed the electric charge of the ground where it hit, making it immune to further strikes. Odds are pretty good that the Torre Ciudadana in Monterrey, Mexico pictured in this shot from summer 2014 has been hit plenty of times.

When it hits, lightning can get up to 50,000 degrees Fahrenheit, meaning the immediate heat of these strikes was pretty toasty. Rods reach out everywhere in this photo taken in a June 2011 storm in Belgrade, Serbia.

While building up equity in a home can be a great long-term investment, in some neighborhoods it makes more economical sense to rent.

Realtytrac, a real estate information company, compiled data on 285 counties nationwide and analyzed the economics of renting instead of buying a home. They found the average cost to rent or own a 3-bedroom house and determined the percentage an average worker would have to spend from their weekly income.

In 66% of the counties Realtytrac found it was more cost effective to buy. But the potential savings in counties where renting was more cost-effective were higher. Most of the counties are in the red-hot California housing market.

We screened for the counties that had populations of more than 500,000 people and where a renter would save at least 10% more than homebuyers.

Check them out below in order from least to most savings.

In January 2006, NASA launched the fastest spacecraft in history toward the dwarf planet Pluto. Now the spacecraft — called New Horizons— is hastening toward its destination and is scheduled to make its closest approach to Pluto on July 14. 

On that epic day, New Horizons will use its slew of instruments on board to capture images of the distant icy world in unprecedented detail — hundreds of times clearer and thousands of times closer than the Hubble Space Telescope could ever hope to achieve.

Scientists on the New Horizons team have been patiently waiting for this moment for nearly a decade, and now their time is fast approaching. Here are 10 infographics by NASA that will teach you everything scientists know so far about icy Pluto.

Here's a basic introduction to the dwarf planet and the spacecraft that will uncover its secrets.

We mentioned that New Horizons was fast. Well, here's just how fast:

This shows what will happen in the days leading up to and following New Horizon's flyby of this frigid world:

Journalist Napoleon Hill set out to uncover the key to wealth around 80 years ago, which resulted in his bestselling 1937 book, "Think and Grow Rich." 

There is no mention of "money,""wealth,""finances," or "stocks" within Hill's text.

Rather, he focuses on breaking down the mental barriers that prevent many of us from attaining our own fortunes, an approach which is still relevant today. 

We scoured Hill's pages to come up with some of his best insights about wealth, power, success, and overcoming the psychological barriers needed to achieve them.

With a fortune of $33.7 billion, former New York City mayor Michael Bloomberg recently landed on our list of the richest self-made billionaires.

Though his 12-year run as mayor ended in 2013, the billionaire remains as busy as ever, and is spending plenty of money as he goes. After all, he hopes to give away his entire fortune before he dies. 

From his early days working on Wall Street to his generous philanthropic donations, here's how Bloomberg made — and spends — his billions.

Born on Valentine’s Day in 1942, Bloomberg grew up in Medford, Massachusetts, a small town near Boston.

After graduating from Johns Hopkins with a degree in electrical engineering and earning an MBA from Harvard, Bloomberg landed a job at Salomon Brothers in New York City, where he spent countless hours counting out stocks and bonds in the bank’s vault. He eventually worked his way up the ranks and was named partner in 1972.

In 1978, he was put in charge of running the firm’s information technology division — a clear demotion. But he stayed at Salomon for three more years until the company merged with commodity trading firm Phibro in 1981 and let Bloomberg go, along with a severance check to the tune of $10 million.

Cocktail culture is huge right now.

But cocktails — with their bitters, syrups, and fancy sugars — are complex. 

Enter Bartesian, the 'Keurig for Cocktails' that's now raising funds on Kickstarter.

Founded by Canadian entrepreneurs Bryan Fedorak and Jason Neevel, the $299 device will make you a margarita in a matter of seconds.

Bryan came by the Business Insider office last week to show us how it works. Here's what we found.

Bryan stopped by our office while he was in New York last week.

He brought the sole working prototype of the Bartesian. The idea came when a friend suggested — "Hey, you guys should make a Keurig for cocktails."

Like the super-popular Keurig coffeemaker, the Bartesian relies on pods to make drinks.
