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

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.

The misconception that aid falls straight into the hands of dictators largely stems from the Cold War era.

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

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

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