Richard Branson believes the key to success is a three-day workweek 

Billionaire Richard Branson is pushing business leaders to embrace the idea of flexible work arrangements, claiming that with today's cutting-edge technology, there is no reason people can't work less hours and be equally — if not more — effective. Hard work is key, but enjoying what you do and having fun is just as crucial, said the adventurous, fun-loving founder of Virgin. In his international best seller "The Virgin Way: If It's Not Fun, It's Not Worth Doing," he wrote that "fun is one of the most important — and underrated — ingredients in any successful venture."
