You have to dig deep to make great music, and it gets harder and harder. It's a difficult, painful process to reach deep in there and pull out the real gems. And you have to have that little bit of anxiety of, 'Can I really do this? Am I good enough?' You need that in the recipe to really get down in there.
A legacy is a lot of times determined by how people accept your music. And sometimes people's legacy starts late or starts early, or they last a long time or a short amount of time. As a musician, I've never taken an approach of wanting to try to control that because I don't think that I can.
