One of the most important things, actually, when you're playing on grass, is to move.

I wish I could have won a lot more tournaments, but I got injured every time I played well.

Everybody is smarter from outside of the court.

Everything is possible in this life.

Roger [Federer], he brought tennis... one level higher. Normally he toys with everybody. With all respect to other players, he does whatever he wants on the court against them. It's incredible what kind of game he can play.

I've lived my life the way I wanted to, whether scaling the mountains, partying long into the night or having fun playing soccer.

If I was the type of person who had tennis, tennis, tennis all the time and I went to bed and ended up dreaming about tennis, I would go nuts.
