- Insomnia: Good ideas come at odd hours. You've got to be awake when they decide to show up.
- Fear of embarrassment: If you're not afraid of your friends making fun of your work, you'll never be any good.
- Will: A lot of people have talent. Only a few have the will to impose their talent. These people are a pain in the ass and drive everyone around them crazy. But they don't quit till they get it the way they want it.
