Stanislas Wawrinka

As a tennis player, you have to get used to losing every week. Unless you win the tournament, you always go home as a loser. But you have to take the positive out of a defeat and go back to work. Improve to fail better.

You can't underestimate rest. Sometimes in tennis we don't realize that to rest your body is as important as it is to practice. We are traveling so much, all year, in different conditions, different courts, different surfaces, different balls - so we always have to adapt.

Set your sights high, the higher the better. Expect the most wonderful things to happen, not in the future but right now. Realize that nothing is too good. Allow absolutely nothing to hamper you or hold you up in any way.

I remember Detroit feeling really unsafe, feeling scared a lot. Our house was broken into, our car was stolen, we had to get a watchdog, we would get beat up in the street, I had my bike stolen. There was just a lot of real anarchy on the streets and sidewalks.
