I have no control over what people think of me but I have 100% control of what I think of myself, and that is so important. And not just about your body, but so many ways of confidence. You're constantly learning how to be confident, aren't you?

I can't do the same movies all my life. I'm conscious of that. But it's a trade-off. 'Dear John' allowed me to do movies I've wanted to do. You learn to balance it out. I'm still learning. Only now am I getting to do the kinds of movies that I have wanted to do. So it's a steady climb. You don't jump into a Soderbergh film.

To be proud of learning is the greatest ignorance.

I've always loved music, but I never really played anything. After 'Walk the Line' and learning to play guitar, and having that sense of performing, I think that certainly opened the door for me, for music.

I'm pleased to say my knee feels a lot better. It's still not back to normal, and I don't know if it ever will be, but I'm learning to deal with it instead of expecting it to be like it was before.
