Unless you're involved with thinking about what you're doing, you end up doing the same thing over and over, and that becomes tedious and, in the end, defeating.
People say to me, 'Oh, being a mother must make you a better actor,' and I think, 'Well, I never sleep, I have very little time to think about anything except when I'm actually there.' I wonder whether that makes me a better actor. I think it must on some level.
In an age of incompetence, I've been able to last in this crazy business. I actually know how to play my ax and write a song. That's my job.
