Training the body to obey the mind as I have done differs from the more conventional method of getting the mind to obey the body.

When I play, I'm boiling inside. I just try not to show it because it's a lack of composure, and if you give in to your emotions after one loss, you're liable to have three or four in a row.

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

You can't give up! If you give up, you're like everybody else.

Ninety percent of my game is mental. It's my concentration that has gotten me this far. I won't even call a friend on the day of a match. I'm scared of disrupting my concentration. I don't allow any competition with tennis.

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

I've had a lot of fear in my life, from fear of flying to fear of making a speech in front of a lot of people.
