Effective philanthropy requires a lot of time and creativity - the same kind of focus and skills that building a business requires.

I actually thought that it would be a little confusing during the same period of your life to be in one meeting when you're trying to make money, and then go to another meeting where you're giving it away. I mean is it gonna erode your ability, you know, to make money? Are you gonna somehow get confused about what you're trying to do?

Philanthropy should be voluntary.

I don't have a magic formula for prioritizing the world's problems.

The most amazing philanthropists are people who are actually making a significant sacrifice.

Corruption is one of the most common reasons I hear in views that criticize aid.
