Segway polo is apparently a thing.

Successful people usually don't get to where they are without a whole lot of hard work, a ruthless determination and a solid slice of luck. However, even with this work hard ethic, it's important to take a moment every now and then to play hard as well. After all, you have to take some time out from the stress of running a Fortune 500 company or reading endless lines to partake in a bit of relaxation. 

While most of us are happy to watch a film or head to the pub to unwind, successful people tend to be inspired by unusual past times. From playing World Of Warcraft to competing in Segway polo (yes, it's a thing), here are the weird and wonderful hobbies of a variety of successful people. Maybe you'll find a new hobby or two as well.

If Mumford & Sons is ever looking for a new ukulele player then they need to look no further than legendary businessman Warren Buffett.

He even rocked the stage at the Forbes 400 Summit with Jon Bon Jovi. He tends to use his hobbies for good, donating signed ukuleles to auctions to raise funds for a variety of charities. 

Bill Gates Plays Bridge

American actress Amanda Seyfried has starred in a number of big-budget films over the years but it seems her low-key talent lies with knitting. Seyfried is an amateur knitter and shares some of her inspiring creations via her Instagram. She's not the only unexpected knitter, with Academy Award winner Glenn Close, Jessica Jones' actress Krysten Ritter and former WCW Champion David Arquette all also equally fond of crafting the occasional scarf and cardigan.  

Albert Einstein Loved Sailing

One of the greatest scientific minds of all time, Albert Einstein loved nothing more than taking to the water in his sailboat. Einstein enjoyed the tranquil surroundings and the feeling of solitude provided by sailing, stating that they enabled him to clear his mind and stop thinking about equations for a few hours. Surprisingly, Einstein wasn't all that great of a sailor. The man known for developing the Theory of Relativity was also known for capsizing his boat in the lakes and rivers around New York and New Jersey.

There are few entrepreneurs as entertaining as Sir Richard Branson. The founder of the Virgin Group has made a career out of smart business decisions and over-the-top marketing stunts, so realising he enjoys hobbies like kitesurfing ties in with his infectious personality. Speaking with Surfer Today Branson described how the sport enables him to clear his mind before a day of wheeling and dealing in the boardroom. "I will kitesurf if the wind's up, get half an hour away from Blackberries and iPhones, then comeback completely refreshed ready to go."
