I don't like the word 'career'. When somebody says to me, 'oh, you've had such a wonderful career', I think, 'career - that's after you're dead.' I just don't think that way.
Take a play that you like but you think is flawed, and see if you can improve it and turn it into a musical. Then make up your own story.
When I listen to my work, I think, what's so inflammatory about it? It's not really that dissonant. A lot of people who used to hate my stuff have come round to it.
If people have split views about your work, I think it's flattering. I'd rather have them feel something about it than dismiss it.
