10. Richard Branson says the key to success is happiness.
“So many people get caught up in doing what they think will make them happy but, in my opinion, this is where they fail. Happiness is not about doing, it’s about being. In order to be happy, you need to think consciously about it. Don’t forget the to-do list, but remember to write a to-be list too.” – Richard Branson’s “Tips for Happiness” (Virgin)
