I don't feel I was ever a 'famous' child actor. I was just a working actor who happened to be a kid. I was never really in a hit show until I was a teenager with West Wing playing First Daughter Zoey Bartlet. In a way, that was my saving grace - not being a star on a hit show. It kept me working and kept me grounded.

Looking back, I feel like I was really young, and at the time I didn't think that I was that young. It was extremely traumatic and awful and horrible. At the same time, it turned out for the best. I'm glad that I'm not there. I'm glad that it didn't happen when I was 50. I'm glad I didn't have kids. And I got that out of the way. Hopefully. Like, that's probably not going to happen again.

Anytime you have a female protagonist, it's going to turn into some feminist angle, and it's not a conscious thing on my part. It's only recently that that's been pointed out by the media . . . or pointed out by fans. I also find complicated, flawed characters interesting. What's the opposite? To play one-dimensional, boring failures?

I don't think any of us could have possibly anticipated how successful Mad Men has been. When we were working on the pilot, we loved it. We thought it was special. We hoped and prayed it'd be a success. But, we didn't count on it.

One day you're there and then all of a sudden, there's less of you. And you wonder where that part went. If it's living somewhere outside of you. And you keep thinking maybe you'll get it back. And then you realize it's just gone.

At 15, you have to decide if you're going to go into professional dancing and really pursue it. I just a) knew that I couldn't stop acting, and b) I had that sort of foresight to understand that when I was 35 - if I was lucky and if I hadn't gotten injured - my career would be on its way to ending. Now, at 34, I really understand that. But at 15, I understood that as well. I was like, "I can't. That's just too risky.".

Twitter scares me. I think it's so amazing, like the internet in general, because of the connection that it gives people. But the concept that one 140-word post can change someone's life . . . that scares me. You can literally ruin someone's life with one tweet. So I only do Instagram. I love photography . . . and interacting with the fans. I do love hearing from them. I try to answer questions if I can.
