Losing hurts me.

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

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

Every time, all the time, I’m a perfectionist. I feel I should never lose.

You’re always striving to play that perfect match.

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.

If I win several tournaments in a row, I get so confident I’m in a cloud. A loss gets me eager again.

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.

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

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