Be who you really are.

I have to believe in myself. I know what I can do, what I can achieve.

There have been times when you doubt yourself. You don't know if you're working on the right things.

I am competitive, and I like to be as competitive as possible in anything I do.

I do things with a lot of feeling.

Concentrating for four hours will wear you out mentally.

I definitely don't consider myself a kid anymore. I feel like an old man, an old 28-year-old.
