Bill Gates: I'd Give This Book to Every College Graduate

Bill Gates may be a college dropout himself, but he's still hit up for advice quite a bit from college graduates. In a series of tweets spotted by Business Insider, Gates is offering that advice to all. Among other things, he writes that if he were a college freshman today, he would study artificial intelligence, energy, and the biosciences, all "promising fields where you can make a huge impact." Some other nuggets:

• A regret: "I also have one big regret: When I left school, I knew little about the world's worst inequities. Took me decades to learn."

• On happiness: "Like @WarrenBuffett I measure my happiness by whether people close to me are happy and love me, & by the difference I make for others."
• A gift: "If I could give each of you a graduation present, it would be this--the most inspiring book I've ever read." The book is Steven Pinker's The Better Angels of Our Nature.
