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.

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

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?

The world is full of what seem like intractable problems. Often we let that paralyze us. Instead, let is spur you to action. There are some people in the world that we can't help, but there are so many more that we can. So when you see a mother and her children suffering in another part of the world, don't look away. Look right at them. Let them break your heart, then let your empathy and your talents help you make a difference in the lives of others. Whether you volunteer every week or just a few times a year, your time and unique skills are invaluable.

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.

Connect deeply with others. Our humanity is the one thing that we all have in common.

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.
