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.

Punish France, ignore Germany, and forgive Russia.

The first step for a leader is to be right with yourself. Integrity is the basis of leadership.

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.

We need to fight protectionism with everything that we have because when there's a level playing field and when you have open markets and when free trade is flourishing, American workers, American farmers, Americans are going to benefit.

The most important lesson I think I could impart is don't let anyone determine what your horizons are going to be. You get to determine those yourself. The only limitations are whatever particular talents you happen to have and how hard you're willing to work. And if you let others define who you ought to be, or what you ought to be because they put you in a category, they see your race, they see your gender and they put you in a category. You shouldn't let that happen.

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.
