I have never given away a penny

I have never given away a penny that has affected my life in any way, shape, or form. There's people will drop $5 in the collection plate, difference between for dinner or go to a movie. I've never done any of that. But if you have this incredible surplus, and in our Giving Pledge, we call these— we call on people with a billion, and I'm only asking for half. So I, I say to them, "I'm going to write on $500 million because there's apparently a big need. I found $500 million. All the rest, and all the rest is surplus. And why not? If it can provide vaccines, or education, or a better life for women, I mean, why not use it?
