Well-spent aid money is saving lives for a few thousand dollars per life saved.

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

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

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

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?

Although I don't have a prescription for what others should do, I know I have been very fortunate and feel a responsibility to give back to society in a very significant way.
