Bill Gates is retiring

Bill will still be the chair of Microsoft, but he's going to step away from his executive role. He wants to spend more time with his charitable foundation.

When you're worth $50 billion, how could you not want to be more interested in trying to have a positive impact on the world? I would do that in a heartbeat. In fact, I would've probably done it years ago if I were him. We can all do our part at the local level, and that's great, but imagine being so loaded that you can single handedly immunize a small country against a disease or drop several new buildings into a university. I honestly wouldn't know where to start!
