Stanislas Wawrinka

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.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.

People have this idea that the more pious and devout I am, the more successful I am. Which is very dangerous. If you look at faith in that way, you're bound to fail at both - spiritually and in your career.
