I think I still have a great sense of adventure and trust, and am surprisingly idealistic given all the horrible things I've seen since I was 25. I think how I have changed is that I have a much deeper understanding of the dark forces in the world, of power.

I feel like I'm a relentless, pragmatic, determined optimist.

I have seen that traditional approaches to charity and aid don't solve problems of poverty. In fact, too often they create dependence.

1.5 billion people lack proper access to electricity. Many buy kerosene, which can cost 30 percent of their income. It sends millions of metric tons of carbon dioxide into the atmosphere every year. And often the lamp will fall over and catch the house on fire. So mothers hate it, but it's their only option.

After all this atrocity, this is how human beings really pray.

Philanthropy is no longer about writing a check for $10,000 to the opera.

All people deserve access to health at prices they can afford.
