Tocqueville talked about "ceaseless agitation," citizens constantly use their institutions, constantly challenging them, constantly insisting upon their rights. It's also individuals taking responsibility for other individuals, recognition that no democracy works if they're weaklings.

I know that people look at my life and ask, "How can I achieve some of those things?" So, I suppose in that sense, yes, I'm a role model. But I try to think of myself more as a mentor, as somebody who I hope young people feel comfortable approaching or writing to.

Our effort to build stability through authoritarians in the Middle East for 60 years had given us neither democracy nor stability.

But we do have confidence in our institutions. We are not Russia. We have an executive that is constrained. We have a legislature that is real. We have a press that is free. We have courts that are independent. This is not Russia.

I believe our Presidents work hard and it's the loneliest job in the world.

I never found anybody I wanted to spend my life with. People say, "Didn't you want to get married?" Well, sure, but it's not abstract, there has to be someone you want to marry. I'm pretty traditional. Marriage would have to come first, before kids.

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.
