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

We've organized human potential and have been better at using human potential better than any country on the face of the Earth. That's because we've recognized that our national creed, our national identity, is that it doesn't matter where you're from, it matters where you're going. You can come from hard circumstances and do great things. We've got to make that true for a whole variety of people who no longer feel that.

I do have a favorite Zeppelin song, Larry, Black Dog.

I think that one of the greatest challenges we have today is around education. One of the things that is dividing us more and more is whether you have good prospects or you don't. Do you live a neighborhood where the schools are good? If you don't, your kids may not read until the time they're in third grade. Do you at least have access to a community college that will give you job training skills so that if you don't go for four years you will at least come out with a decent job and a decent wage. Too many people don't have that opportunity.

We have important things to talk to the Russians about, despite their meddling in our elections. I hope they're talking about a way to eventually end this horrific humanitarian crisis in Syria, end that war. The Russians have more leverage than we do. I hope they're talking about the fact that, if Kim Jong-un's long-range missiles can reach Alaska one day, they can also reach Vladivostok.

What you know today can affect what you do tomorrow, but not what you did yesterday.

I learned a lot about my parents, who were both teachers. I had known that my parents were very strongly in favor of education. I had known that they had an impact on a lot of people, but people came out of the woodwork who have said, "You know, without your father, I would never have gone to college," very successful people. And so I learned how widespread their educational evangelism really was.
