Single-mindedness. I hate to say it because I don't think it's the best thing for developing a person, but the single-mindedness - just concentrating in the one area - that's what it takes to be a champion.

I still have this image: I can't be controversial, I can't say things.

I'm not an overly ambitious person; I don't feel like I have to excel.

I was labeled at a young age - Miss Unemotional, Miss Cool, and that would carry over to my press conferences.

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.

Don’t let a first-set victory lead into a second-set slump

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.
