My most important identity now is as a mother.

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.

He has always provided me a safe place to land and a hard place from which to launch.

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.

Patience is a virtue, but impatience gets things done.

I hope telling stories though 'Making a Difference' - as in my academic work and nonprofit work - will help me to live my grandmother's adage of 'Life is not about what happens to you, but about what you do with what happens to you.'

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