Questioning my spiritual life has always been germane to what I was writing. Always. It's because I'm not quite an atheist and it worries me. There's that little bit that holds on: 'Well, I'm almost an atheist. Give me a couple of months.'

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.
