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.

If I really believe all lives have equal value, and if I use contraceptives, which I do, and if I'm counselling my son and my two daughters to use them, how am I not serving the women who don't have access to the contraceptives they need?

If we don't empower women, we don't allow them to unlock the potential of themselves and their children.

Women are the centre of the family. It's the woman who decides what's eaten in the house, when to have the kids vaccinated; everything that has to do with the children's health revolves around her.

You can have the best vaccines for a woman or her child, but if you can't get her to come and get them then they won't work.

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

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.
