For me it's just so exciting to have a daughter because I do think she will have even more opportunities than I had, and I had more opportunities than certainly my grandmother had. It's the arc of history, always bending toward justice and opportunity, and she will be part of that.

I think we need to care about the metrics of success in life, and I'm a pretty competitive person.

I know I'm late, but I've finally joined Facebook!

We proved we could be safe and secure at home, and still have more allies and friends in the world.

Over the summer I thought that I would seek out non-Americans as friends, just for diversity's sake. Now I find that I want to be around Americans - people who I know are thinking about our country as much as I am.

My grandmother was determined that everyone feel a sense of optimism and opportunity. Marc and I want to make sure we're doing that. This period of our lives is not just a tribute to her, it's inspired by her. And it's for when we have our own children — I want to help make sure we've got a world I want them to live in.

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.
