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

Intellectually, I loved my job, but I didn't get any meaning from it.

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 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.

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.

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.

You'd better talk to my dad. My mom's pretty busy.
