I woke up. I was like, "Look, you can do anything you want - and you want a lot of things, so you should get to work."

I'm sure everybody looked at me cockeyed. But if you don't believe it, then it's not going to happen. If you don't believe it, no one else is going to believe it. But if you believe it and keep saying it, then slowly one person will believe you, then two, then three, then four . . .

You have to be dynamic. You have to be able to change. So a lot of times we'll go to a country or go meet people, and then while we're there, the story changes and you have to be able to go with that. And then the story comes out in the editing room, which is a very documentary sort of process - not how news works. So that's different.

I don't care if I die - look, I'm old - but you want your kids to have good times and a good life. I became sort of aware. I used to get so angry.

I was getting mad at the system or the politicians or the government, and then I realized someone should talk about this stuff, and I have a big, multinational global-youth platform of kids who are going to change the world. So I was like, "I should be doing that. I should be showing this to people. That's my job." And since that time, I've been very happy.

The greatest propaganda coup of the American right has been to convince its citizens that we are in the grip of a liberal conspiracy.

Success. Money. Fame. Whatever you're going after. You have one kick at the can, I always say. It's very rare that you have many kicks at the can. You're there at the right place at the right time, you have your shot, and it either works or it doesn't. And I've had many shots.
