The advice I tell students is to think about the big problems. I mean, work on anything you can work on where you can make progress. But always keep in mind the big problems.

We've made a lot of progress, but we also know there may be further problems, and we're going to work night and day to solve them. We've redoubled our focus on who's available to work on these problems.

Our progress as a nation can be no swifter than our progress in education. The human mind is our fundamental resource.

I hoped that students would emotionally connect to the people and problems they saw around them and want to do something about it.

The title always comes last. What I really work hard on is the beginning. Where do you begin? In what tone do you begin? I almost have to have a scene in my mind.

The campaign commercials don't tell you anything.
