I really do fervently believe that every child deserves to have the kind of access to educational opportunities, broadly defined, including music and sports, that I enjoyed. So, I'm trying to do my part, and I believe that all of us with a privileged background who are fortunate enough to have had that kind of access have a responsibility to try to pass it on.

I'm actually genuinely optimistic about the United States and what's possible in the United States. And when you're out here, you see Americans across racial and economic and socioeconomic lines working together. And you maybe get a little bit less cynical than when you sit in the seat of kind of the epicenter of it all.

It's bad policy to speculate on what you'll do if a plan fails when you're trying to make a plan work.

If you're always in the company of people who agree with you, you're going to think of people who don't agree with you as venal or stupid. I constantly tell my students that if they're in the company of people who always say "amen" to what you say, find other company. And that is the source of illiberalism, when you are unable to listen to someone who thinks differently. That's when democracies are in trouble.

You can never ask others to do something you would not do. That is integrity.

Every life is capable of greatness.

it is a longstanding principle that sitting national security advisers do not testify before the Congress.
