The Middle East is hopeful. There's hope there.

A lucky person gets up in the morning, puts both feet on the floor, knows what they're about to do and thinks it still matters.

I know what I believe, I know what I want to do, and I'm just comfortable saying it, and laying it out there.

Should we have border security there? Yes. But the idea of the United States erecting a wall for the world to see makes a lie of everything we say about ourselves. It's a little bit like why the President [Barack Obama] and I feel so strongly about closing Guantanamo. It is inconsistent with who we are.

Everyone plagiarizes me. Ever since I wrote my autobiography.

We have the greatest resource universities in the world, the only place in the world. We have the most productive workforce in the world. We have the most agile venture capitalists in the world. We have a situation where right now in the United States of America, we are near energy independent. North America is beginning to be the epicenter of energy. What is it that makes people think that this is not going to be the American century? I don't get it.
