Musicals are hard for me because I got thrown out of the glee club in high school, because I couldn't sing in tune at the time. I can sing in tune now, but I have to work really hard on it to make sure that I don't exercise one of my great talents, which is the ability to sing in three keys at the same time.

When I studied how to think in school, I was taught that the first rule of logic was that a thing cannot both be and not be at the same time and in the same respect. That last note, “in the same respect,” says a lot. As soon as you change the frame of reference, you’ve changed the truthiness of a once immutable fact.

When I started out as an actor, I thought, Here's what I have to say; how shall I say it? I began to understand that what I do in the scene is not as important as what happens between me and the other person. And listening is what lets it happen. It's almost always the other person who causes you to say what you say next. You don't have to figure out how you'll say it. You have to listen so simply, so innocently, that the other person brings about a change in you that makes you say it and informs the way you say it.

In 2003, I almost died of an intestinal blockage when I was on a mountain in Chile, filming a segment for 'Scientific American Frontiers.'

I was always interested in figuring things out. I'd do experiments, like combining things I found around the house to see what would happen if I put them together.

I was a child, and my mother was psychotic. She loved me, but I didn't really feel I had a mother. And when you live with somebody who is paranoid and thinks you're trying to kill them all the time, you tend to feel a little betrayed.

There are two things that I get a lot of pleasure from in my life, and that is, doing what I know how to do well - that really makes me happy. The other one, and probably an equal pleasure, is finding out how I can be helpful and then really being helpful.
