The great high of winning Wimbledon lasts for about a week. You go down in the record book, but you don't have anything tangible to hold on to. But having a baby -- there isn't any comparison.

You pay a price for everything in life.

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.

Once you've been number one, you can never be satisfied with less.

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.

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

I realized that with hard work, the world was your oyster. You could do anything you wanted to do.
