Be who you really are.
I am competitive, and I like to be as competitive as possible in anything I do.
I definitely don't consider myself a kid anymore. I feel like an old man, an old 28-year-old.
Concentrating for four hours will wear you out mentally.
I've heard people say my swing's not perfect, and I know that. But golf's a natural sport, very sensitive. It's played a lot by feel. I don't care if my swing is too flat. If it works, I don't have to change it.
At the end of the day, the only thing I can do is keep working on it, keep giving myself chances, and it's going to happen.
