What great changes have not been ambitious?

I think the Americans need to understand that a lot of times the children are bored in school, and that is why they are not staying in.

I've travelled extensively in the last 16 years - to slums in Bangladesh, to townships in South Africa, to all kinds of places in India, etc. When I would go and talk to villagers about something like vaccines, if I stayed long enough, the women would bring the conversation around and say: "What about this family planning tool? We can't keep having the number of children we're having."

Around the world we have girls in primary school at about the same rate now as boys, but keeping them in quality secondary schools is where the world is lagging. I'm seeing a lot of countries look at this now.

We have to be careful in how we use this light shined on us.

Helping people doesn't have to be an unsound financial strategy.

It's really one of my all-time favorite things to do. To go out and really see the kids and visit the moms who are in these programs because I think I really get to see what happens on the ground and connect with them about what changes are that happen in their lives because of some of the giving that we're able to do.
