Helping people doesn't have to be an unsound financial strategy.

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

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

Microsoft certainly makes products for the Macintosh.

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.

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.

Now, as smartphones are coming up, there are all kinds of apps that will start to be developed that will help women.
