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.

When I first held my daughter, right after she was born, I felt like it was the moment I'd been waiting my whole life for, and it just felt even more miraculous than I ever could have imagined.

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

I am excited to work with NBC News to continue to highlight stories of organizations and individuals who make their communities and our world healthier, more just and more humane.

Thinking about the world writ large, I am more optimistic than not that we will tackle our most pressing challenges, whether poverty or equality for women and girls or climate change; but I also know we'll only tackle them if people are really informed about the challenge and what's proven to work.

I've tried really hard to care about things that were very different from my parents. I was curious if I could care about [money] on some fundamental level, and I couldn't. That wasn't the metric of success I wanted in my life. I've talked about this to my friends who are doctors and whose parents are doctors, or who are lawyers and their parents are lawyers. It's a funny thing to realize I feel called to this work both as a daughter and also as someone who believes I have contributions to make.

I'm a big health-food freak and a vegetarian devotee.
