In actor's career, I had a fair amount of denial, which I think is possibly in the genes, where I just couldn't go to, "Maybe this won't work out." I just couldn't do it. My mind just refused to go there. I don't mean there weren't low periods. There were plenty. But I remember arriving in New York and I was maybe 32, and I didn't have an agent. I came from Chicago, where I had gone to school and worked and got my sea legs, so to speak, and I remember walking out of the subway, walking the streets, standing in front of the theater and saying, "I will work in this theater."

The lovely thing is that now being offered things is just a blast. In the beginning, I'd be offered something and be like, "What? What do you mean? Are they sure?" And now, I have less shock about it. It's just a real pleasure. It's a privilege.

The first day of shooting, you always want to turn around and go home and say, "What was I thinking?!," and put your head under a pillow and weep. I could maybe go five weeks, and then the nerves would set in about when the next job was going to happen.

Damon Lindelof is hypnotizing. His imagination is without limits, and Tom Perrotta, as well. You begin to just trust, completely, where the story is going, knowing that you're entirely safe in the truthfulness of it.

I think aging is underrated. As you grow older, you have perspective and you realize just how fortunate you are to be working. To be working with the people I've had the chances to work with, I honestly feel like the most fortunate person in the world. I think it's hugely important when you work to bring with you that spirit, which includes and immense sense of gratitude. How that translates into behavior is just to bring your energy, your good spirit and your appreciation, and do your homework and really listen to the person in front of you.

To me, being an actor is the best job in the land, next to being a mother and having a family and a husband. I just think it's the realization of, "Hey, this is the greatest situation in the world."
