This outspoken multi-billionaire started out by founding a provocatively named record store, Virgin Records, from nothing. Branson then magically grew that venture into an empire of wildly successful airlines and telecommunications companies. Next on Branson's agenda: transporting civilians to outer space. Not only has Branson admitted he's smoked pot regularly during his uber-successful career, he now shares the pastime with his adult son who's in his 20s. A strong supporter of worldwide pot legalization, Branson said he'd sell weed if that comes to pass. No doubt it would add to his list of victories.
