I was very, very shy as a younger girl, just petrified of people. Tennis helped give me an identity and made me feel like somebody.

To be a tennis champion, you have to be inflexible. You have to be stubborn. You have to be arrogant. You have to be selfish and self-absorbed. Kind of tunnel vision almost.

You've got to take the initiative and play your game. In a decisive set, confidence is the difference.

My first U.S. Open I think was just very special for me because that was sort of the beginning of what was a 'Cinderella' story for me.
