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. John P. Hussman of Hussman Funds said that though Benjamin Graham — Buffett's mentor — was not talking about Buffett at the time, he does explain perhaps why Buffett periodically plays bridge.

“I recall to those of you who are bridge players the emphasis that bridge experts place on playing a hand right rather than on playing it successfully," said Graham. "Because, as you know, if you play it right you are going to make money and if you play it wrong you lose money — in the long run.”

Larry Ellison, the former CEO of Oracle with a fortune estimated by Forbes to be around $48 billion, said his hobby is sailing. In 2013, he and his team won the America’s Cup yacht race for the second time.

He said, "It's funny, because I realized after losing twice that my personality wouldn’t allow me to quit while losing. And then after winning the America’s Cup, I discovered my personality doesn’t allow me to quit while winning. I don’t smoke, but I do sail,” reports Business Insider.

The Huffington Post co-founder and editor-in-chief takes her sleep seriously. "Actually, one problem with our culture is that we are entirely sleep-deprived," she said.

Bill Wyman, former bassist of the Rolling Stones, must surely have one of the oddest hobbies out there: metal detecting. "Metal detecting is not just for anoraks or eccentrics; it's probably the best and most enjoyable way learning about our history," said Wyman in a press release announcing the Bill Wyman Signature Detector. He's the perfect example of someone who was able to turn their hobby into a money-making machine.

The "X-Factor" judge and former "American Idol" judge hobbies mirror those of a 10-year-old boy. Simon Cowell told Nancy O'Dell from "Entertainment Tonight," "I climb trees, daily."

Justine Musk, ex-wife of Elon Musk, told the New York Times that work is Elon's hobby. But take a minute to look at what he does, and then maybe it won't be so difficult to understand why: Elon was the co-founder of PayPal and founded SpaceX, which designs, manufactures and launches advanced rockets and spacecraft. One top of that, he is the current CEO of Tesla Motors. According to Forbes, Elon has an impressive net worth of $13 billion — it looks like his "hobby" is paying off big time.

Angelina Jolie’s hobby is collecting daggers. She told W magazine in 2008 that her mom took her to buy her first daggers when she was 11 or 12. She introduced her eldest son, Maddox, to the art of dagger collection at a young age, but emphasized that the knife blades are dulled so they are not dangerous. Jolie also said that she accompanies knife purchases with discussions about violence, and “we also talk about samurais and about the idea of defending someone as good.”

Here's another billionaire who turned his hobby into a job. Before buying the Dallas Mavericks NBA team, Mark Cuban was a dedicated basketball fan.

I can do a better job than this." Cuban has since become a huge voice in the sports world.
