When we better understand the realities of these women's lives, we are able to design and deliver solutions that are more useful to them.

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.

That's universal - we all want to bring every good thing to our children. But what's not universal is our ability to provide every good thing.

I am inspired by the women I meet everywhere I go. They have to work so hard just to make sure their families survive, but somehow they stay optimistic and do everything in their power to make the future better than the past.

In the developing world, they don't have smartphones yet. They have the older plastic phones, but women are saving money on those, because they don't have access to banks. Having that access to digital money changes everything for her because she actually doesn't have to negotiate with her husband, which she will tell you is very hard in these circumstances, especially when the means are meager. She's expected to have money to pay for the kids' health or to help with the school fees.

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?

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