Our desire to bring every good thing to our children is a force for good throughout the world. It’s what propels societies forward.

Sometimes it's the people you can't help who inspire you the most.

We [with Bill Gates] started to make decisions about what we'd invest in. Then I actually started traveling for the foundation. I've probably been to India now eight times at least and Africa numerous times.

Government funding that's coming from the United States is making a huge difference on the ground in the developing world. It's really palpable - it's making a huge difference saving lives.

Women and girls face a whole host of issues. We start with health, so we work very deeply on maternal deaths, making sure that a mom doesn't die in childbirth, making sure that she has access, for instance, to AIDS medication.

I'm happy we have three healthy children and we'll stay with three healthy children.

Even in our own agriculture strategy, if we got a great new drought-resistant seed and we managed to get it distributed in the system, we just assumed that it would reach female farmers. That's a false assumption, because women don't interact with agro-dealers. So if you don't develop specific programming to ensure that seed gets in a woman's hands, then the extra income [generated by higher-yielding crops] goes into her husband's hands.
