I was a different kind of player as a kid and didn't do too much shouting and screaming. If things didn't go my way, I tended to get a bit overwhelmed. All I wanted to do was cry on my mom's shoulder. I didn't know how to handle defeat in front of a crowd, and I didn't want to be the loser.

I just remember watching Federer the first year he won Wimbledon. He was struggling with his back problem. I remember it vividly. It looked like there was a chance he was not going to finish. He had that look in his eye. Then, somehow, he found the wherewithal to dig a little deeper, and suddenly he wins the thing, and he's a different player.

Tennis was a white, upper-class sport, and I wanted it to be treated like other sports were.

You hit a wall at some stage when you don't want it so bad, but you don't know when that's going to be - as far as competition or as far as health is concerned. Sometimes it's just natural. You just taste it, and you want it so bad that you find other gears.

The only thing 'championship' about Wimbledon is its prestige.

The important thing is to learn a lesson every time you lose.
