You know when you're young and you see a play in high school, and the guys all have gray in their hair and they're trying to be old men and they have no idea what that's like? It's just that stupid the other way around.
I've always felt that if I examine myself too much, I'll find out what I know and don't know, and I'll burst the bubble. I've gotten so lucky relying on my animal instincts, I'd rather keep a little bit of the animal alive.
As you get older, you're not afraid of doubt. Doubt isn't running the show. You take out all the self-agonizing.
If a person doesn't change, there's something really wrong with him.
