We also ought to recognize that unpaid labor falls predominantly to women. The other thing I would do in countries like the U.S. is to show more men, even in TV ads, doing household work. Only two percent of ads show men doing chores, and yet we know they actually do several hours of it in real life. Those images affect young boys and girls.

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.

When I look at 225 million women who want contraceptives, and then I look at the 52 million unintended pregnancies that could be avoided by addressing this unmet need, where can we have the biggest impact with our voice, our dollars, our partners? It's on contraceptives. I would rather address the problem upstream.

If you can't travel to the developing world, look at helping to fund a woman with a small loan and follow her. Learn her story. Learn about the difference that you're making.

I think it's very important that we instill in our kids that it has nothing to do with their name or their situation that they're growing up in; it has to do with who they are as an individual.

When I studied computer science at Duke University in the first half of the 1980s, I had professors who treated women differently than men. I kind of got used to it. At Microsoft, I had to use my elbows and make sure I spoke up at the table, but it was an incredibly meritocratic place. Outside, in the industry, I would feel the sexism. I'd walk into a room and until I proved my worth, everyone would assume that the guy presenting with me had credibility and I didn't.

Microsoft certainly makes products for the Macintosh.
