You fight, you try your best, but if you lose, you dont have to break five racquets and smash up the locker room. You can do those things, but when youve finished, nothings changed. Youve still lost. If something positive came from that, I probably would do it. But I see only negativity.

Two weeks ago, I was in a fantastic situation, winning at Roland Garros. Now, losing in the first round, it's tough. The tour continues. Life continues. This is a sport of victories, not a sport of losses. Nobody remembers the losses. I don't want to remember the loss.

Even if I have already peaked, I have to believe I can improve. I wake up every morning, and go to practice, with the illusion that I'm going to get better that day.

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

I have lived my whole life with high intensity.

I learned during all my career to enjoy suffering.
