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 was working full time and going to school at night and on the weekends. It was just crazy. At one point a month had gone by, and Marc - my then boyfriend, now husband, and I hadn't gone out on a date. I was like, I don't want to be this person. I want to be a person who cares where she's investing her time and energy. And I want to be a good wife, daughter, and friend.

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.

My parents and my grandmother inspire me every day and, every day, in my work and personal life.

Every day at some point I encounter some sort of anti-American feeling.

I hope that young people will also look to politics as a vehicle to not only have their voices heard, but actually to be the change makers that they want to see. They are disaffected, understandably, but I hope that young people will not only turn out to vote but also run for office.

Service is an opportunity for young women to really empower themselves.
