Whether they're hitting the campaign trail or overseeing multibillion-dollar empires, even the world's hardest-working and wealthiest people need time out of the spotlight to recuperate from a long day of work. Click through for a glimpse at some of the hobbies of your favorite celebrities today.
Hillary Clinton — Mystery Novels
A May 2016 NYMag article revealed Democratic presidential nominee Hillary Clinton enjoys mystery novels, notably those written by female authors and including female protagonists. Talk about female empowerment. She and Bill also enjoy watching TV shows like "House of Cards," "Madam Secretary" and "The Good Wife."
Donald Trump — Golfing
It's no secret that Clinton rival and Republican frontrunner Donald Trump loves golf. He's frequently photographed golfing, he's mentioned it on the campaign trail and, oh yeah, he actually owns golf courses around the world.
Warren Buffett — Bridge
Warren Buffett loves to play bridge. He discussed his hobby on CNN Money and said that more than 95 percent of his bridge games have taken place online over the last 15 years. But that doesn't stop the billionaire from playing in-person. In 2007, he was filmed playing bridge with Bill Gates at an annual Berkshire Hathaway meeting.
The Berkshire Hathaway CEO has a net worth of $64.9 billion, which is a measure of assets versus liabilities, reported Forbes. Ranking No. 3 in the Forbes 400 list of the wealthiest people in America, Buffett is a world-renowned investor known for his down-to-earth personality and money know-how.
Meryl Streep — Knitting
Famed actress Meryl Streep, known for films like "The Devil Wears Prada," "The Iron Lady" and "Mamma Mia!," has simple tastes. She enjoys knitting, according to numerous interviews with the star. In a 2014 interview on "Blank on Blank," a PBS series, the Academy Award-winning actress said she even once found an old knitting bag, which had an unfinished sweater for an ex-boyfriend.
However, knitting is not her only hobby. An interview with The Talks revealed Streep does most of her own cooking, though she had someone cook meals for her and her family when her children were younger.
The actress lives a rather frugal life, she told TheRecord.com in March 2015. "I live a very unspectacular life," she said. "I love to sit on my chair in the living room and knit. Or I cook or read a book. I'm a very frugal person."

Larry Ellison — Sailing
Larry Ellison, co-founder and CEO of Oracle, has a $49 billion fortune, according to Forbes. His hobby of choice is sailing — and he's really good at it. In 2013, he and his team won the America’s Cup yacht race for the second time in a row.
"It's funny, because I realized after losing twice that my personality wouldn’t allow me to quit while losing," he told Business Insider in 2014. "And then after winning the America’s Cup, I discovered my personality doesn’t allow me to quit while winning."
Arianna Huffington — Sleeping
Hobbies don't have to be complex or extreme, as proven by Huffington Post co-founder Arianna Huffington. In a December 2010 Ted Talk, she said, "I learned the hard way the value of sleep." She fell asleep at her desk, she explained, and broke her chin. In her talk, she said that there is a culture of one-upmanship when it comes to how busy we can be and how little sleep we get.
Taylor Swift — Baking
Multi-Grammy award-winning singer and songwriter Taylor Swift has done more in her young life than most people could dream of doing in a lifetime.
