When I was younger I really admired people like Warren Beatty who could do one movie every four years. I thought I could do all that: run a theatre company, write a book, make the occasional movie. But life doesn't work like that, or at least it only does for one or two people every generation. Usually, there's a little give and take, you know. It took me a long time to realise that I didn't understand things as well as I thought I did.
