Human beings do things for a reason, even if sometimes it's the wrong reason.

A lot of people would flee from what they think is award-show cheesiness, and I don't. I often joke that my speeches are very personal moments that play themselves out in front of billions of people.

There was a period of time in Los Angeles when I wondered if I was just going to lose everything.

I love what I do for a living, it's the greatest job in the world, but you have to survive an awful lot of attention that you don't truly deserve and you have to live up to your professional responsibilities and I'm always trying to balance that with what is really important.

My work is really a blast. When it stops being a blast, then it ain't no fun no more!

From now on we live in a world where man has walked on the Moon. It's not a miracle; we just decided to go.

I try to do what I call the three E's - educate, entertain, and enlighten. If you don't entertain, no one will show up. But you also have to educate, because people want to discover specific things about a world unlike their own - whether it's how hard it is to go to the moon or how scary it is to be on Omaha Beach.
