I'm very physical. It's an important part of being a woman - feeling good about yourself and really being in tune with your personality.

There's this certain caliber of dancing I was striving for when I was younger, and it's very hard for me to go back and just do it for fun. But I take all other kinds of classes: I take jazz classes, modern classes, and I love doing that instead of going to the gym. The gym is not very much fun.

There was a little part of me that always felt like I was going to be an actress, but I never acted when I was growing up. I was a dancer. That's all I did, all day, all my life. Maybe this was just where I was meant to be, and somehow I ended up here, but it just felt right. As soon as I started acting, it just felt like it was meant to be.

As I've gotten older, I've come to realize how important it is to vary your workouts.

When I was little, I had a feeling that I was going to end up being an actress. I spent a lot of time alone, I was a very shy girl, and I would pretend I was telling someone about this new role that I got.

Every day on the set, things change. You move things around. The actors are creating the roles and bringing them to life, and bringing the moments to life, as they happen. That's the best thing about television. I think it gets misunderstood, when there's one credit that says, "Written by," because that's certainly not the way it happens, in real life.

I worked on 'Sarah Connor' even longer than 'Firefly.' And I always remembered how generous everyone was to me when I didn't know what to do, and I didn't know the rules, and I didn't know camera angles, and I didn't know lighting.
