Television is such an evolving medium. When you're doing a TV show, it's not like you just shoot for six weeks and you're in an editing room with all of your footage. It's like a guitar or a car, you have to fine tune things. You stop doing what's not working, you work on what is working and you add things that do work.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
