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.

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

That's not what I want my children to hear. That's not representative of the country that I want my children to grow up in. And so that actually I found far more upsetting as a mom, as a woman, as an American, and even as my mother's daughter than anything they said about my mom.

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

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

For most of my life, I deliberately led a private life in the public eye.

My parents always asked me what I thought, listened to my opinions, articulated their diagnoses of our challenges at home and abroad, and shared their ideas for how to build a more equal and prosperous country. I always felt part of their call to serve and part of my father's journey.
