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

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.

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.

If you can react the same way to winning and losing, that's a big accomplishment. That quality is important because it stays with you the rest of your life, and there's going to be a life after tennis that's a lot longer than your tennis life.

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

Not every child is cut out for an individual sport.

Ninety percent of my game is mental. It's my concentration that has gotten me this far.
