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.

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.

Women speaking up for themselves and for those around them is the strongest force we have to change the world.

In the United States, there's definitely some controversy about birth control in general, and I think we needed to split the debate and have people realize that we actually agree as a country about contraceptives. Over 93 percent of American women say they use contraceptives, and they feel very good about it.
