My parents were very firm about me always getting my homework done.

I'm always struck by how innately curious kids are about the world around us and how engaged and sensitive they are to what is happening .. and how many kids do want to be engaged and do what to make a difference.

I really believe that with a little bit of information, kids can make a big difference.

A tin roof is one of the greatest indicators of prosperity in the developing world.

It just seems so fundamental to me. I'm able to marry the person I wanted to marry. That's the fundamental human imperative. Those of us who have been lucky enough should expand these rights to others.

What inspires me most are people who imagine and implement solutions to challenges in their own lives, in their communities, in our country and around the world.

My marriage is incredibly important to me. It's the place from which I engage in the world every day, and the place to which I return every day.
