In the developing world, it's about time that women are on the agenda. For instance, 80 percent of small-subsistence farmers in sub-Saharan Africa are women, and yet all the programs in the past were predominantly focused on men.

A-plus players like to work together and they don't like it if you tolerate B work.

I sat in a garage and invented the future.

Mothers might say they'd go to the doctor. In poor countries, moms are usually responsible for their kids' health. But breastfeeding and traveling to the clinic take time, and research shows that health care is one of the first tradeoffs women make when they're too busy.

The fact that 98 percent of women in [the U.S.] who are sexually experienced say they use birth control doesn't make sex any less sacred. It just means that they're getting to make choices about their lives.

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.

When girls are educated and free to pursue their passions, they contribute more to a thriving society. When women have a voice, they raise it to demand a life that is greater than what they've been told they have a right to expect. And these demands change the future for everyone.

Think, for a moment, about our educational ladder. We've strengthened the steps lifting students from elementary school to junior high, and those from junior high to high school. But, that critical step taking students from high school into adulthood is badly broken. And it can no longer support the weight it must bear.

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.

My background was computer science and business school, so eventually I worked my way up where I was running product groups - development, testing, marketing, user education.

Birth control has almost completely and totally disappeared from the global health agenda, and the victims of this paralysis are the people of Sub-Saharan Africa and South Asia.

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

It is still just unbelievable to us that diarrhea is one of the leading causes of child deaths in the world.

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.

Women around the world should have a tool that helps them plan their pregnancies.

In places like India with smartphones, there's an app now for women if they're in a violent situation, they can press one button. They've given their cell-phone number to five trusted friends, and right away their GPS location goes out: "Here I am."

With economic opportunity, sometimes it's making sure that if they're not in a place where they can have good jobs, that when they have economic opportunity, they have digital tools to use.

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 [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.
