Looking back, I’ve had a remarkable ride. I’m not sure I can call it a career, because a career implies that I had some kind of career plan, and I never did. The nearest thing I had was a list I made when I was 15 of everything I wanted to do: to write an adult novel, a children’s book, a comic, a movie, record an audiobook, write an episode of Doctor Who… and so on. I didn’t have a career. I just did the next thing on the list.
