Being a great physical athlete is wonderful, and you need it at this level to be able to train and prepare accordingly. But the closer it comes time to perform, the ratio switches. When you're in camp, it's 90 percent physical and 10 percent mental. But as you get to fight night, it's the opposite.
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.
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.
