Microsoft founder William H. (Bill) Gates hits 60, a point in life when the man richer than almost anyone on the planet might be considering a third act. For his seismic second, at 45, he stepped back from running Microsoft to focus on philanthropy.
The third would be anyone's guess. Gates hasn't dropped clues to any new aspirations.
The Bill and Melinda Gates Foundation, established in 2000, was his second act, and the Gates have donated more than US $31 billion to support numerous education, public health and anti-poverty initiatives. In 2011, according to Reuters, his charitable giving cost him the title of the world's richest man.
Unsurprisingly, because people are keen to learn the secrets of such monumental success, there is almost no phase of Gates' life that hasn't generated copious copy. While it records every step of his path, it reveals nothing that hints at his aspirations. On the birthday, someone might come right out and ask Gates what is next for him.
