Some CEOs read. Some play golf. Some attend charitable functions. Virgin CEO Richard Branson takes a nice, long bath (rubber duckie not included). Branson flooded Twitter, as it were, with a photo of him relaxing in his tub Thursday morning. The photo linked to a blog post in which Branson offered some sage advice on time management. "Take time out to recharge and think. Some of the best ideas are thought up when you're relaxing," he wrote.
