The Importance of Self-Esteem

I'm a huge believer in low self-esteem. I keep the success because you don't think you're the smartest person there. You're always trying. That's something, if I see some comics, they did it, the bit worked in Denver two years ago and then they'll go, no, I did this in Denver. It doesn't work anymore. They cannot get rid of material. Everything is not funny.
