Is only a tennis match. At the end, that's life. There is much more important things.

I'm only superstitious on the tennis court.

I appreciate a lot in this life; the things you cannot buy. Life is only once.

I always work with a goal - and the goal is to improve as a player and a person. That, finally, is the most important thing of all.

I always had the theory that the most important thing is be happy, enjoy what are you doing, and be fresh mentally.

I only ever run when there's some point to it - say, if it's in a game of tennis.
