That's the key to success, isn't it? It has to be fun.

I never knew I was grunting, it was just part of my strokes.

I think for me, food was a way for me to deal with emotional trouble.

I am lucky to have advisers whom I trust.

I have this terrible dark side to my personality, which playing tennis keeps at bay

I don't believe in playing hurt, in taking injections to cover the pain.

Tennis is so competitive. I guess that's the way it has to be.

I'm about the present.

You have to want to play it all day, every day to get to the top.

I did realize more than ever, after the stabbing, that tennis is a business - a tough business.

I used to pretend that I was Tom attacking Jerry, who was drawn on the ball

Life is not worth living if I cannot have pasta or bread again.

Tennis has to become everything to you if you're going to make it to the top. You have to live it.

I knew that maybe I couldn't be playing again, but I just wanted to get in physical shape.

I've thrown away lots of my old diaries - you never know who might get their hands on them. But I have kept a few notes on the good old days.

I appreciate very much being injury-free.

It shifted attention away from that and Ive never been someone who liked the attention from the media anyway.

It's so difficult to find time besides the tennis.

I never hanker after the past - I prefer to devote myself to new tasks.
