Women and girls should be able to determine their own future, no matter where they're born.

All of a sudden people in the United States start to realize that vaccines make a difference. The controversy and the myth that's there, we're always trying to bust through that. So when I see a disease outbreak, I say to myself, "OK, that'll get people realizing how lucky we are to have vaccines."

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

Men make different investments than women do. Women tend to invest more of their earnings than men do in their family's well-being - as much as 10 times more.

Having children made us look differently at all these things that we take for granted, like taking your child to get a vaccine against measles or polio.

When girls are educated and free to pursue their passions, they contribute more to a thriving society. When women have a voice, they raise it to demand a life that is greater than what they've been told they have a right to expect. And these demands change the future for everyone.

When were you born, who are your parents, where did you grow up? None of us earns these things. These things were given to us. So when we strip away all of our luck and our privilege, and we consider where we'd be without them, it becomes much easier to see someone who's poor and say, "That could be me." And that's empathy.
