Concentrating for four hours will wear you out mentally.

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

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

I always think under par. You have to believe in yourself.

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

Concentrating for four hours will wear you out mentally.

I've been fortunate enough to do pretty well in playoffs. I feel pretty comfortable in them.
