We start with an economic approach. We look at what are the greatest causes of death in the developing world, and what causes the largest amount of disability, which would prevent you from getting a job. A lot of those deaths start with diseases, diseases we don't get in such a great number in the United States.

If you are successful, it is because somewhere, sometime, someone gave you a life or an idea that started you in the right direction. Remember also that you are indebted to life until you help some less fortunate person, just as you were helped.

Now we just really need to do the work, which we're doing, to get contraceptives out to women worldwide.

If you invest in a girl or a woman, you are investing in everybody else.

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.

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.
