Stan Wawrinka

By growing up at a center for people with special needs, I learned to always fight hard to achieve what I want. In this regard, I was incredibly lucky.

As a child, I was lucky to have the support of my parents because starting a tennis career is a very expensive adventure.

I was a little bit lost in my head after winning a Grand Slam. You're like: 'So what's the next goal? What do you want now? Where do you want to be? It's not a problem if you lose.'

Stress is part of your career. You have to accept it and deal with it because there is a lot of emotion in tennis.

The first years when I came to New York, everything was too big and too much. For me, it was too difficult here, but bit by bit, it became one of my favorite places.

I like Chennai very much. The atmosphere is always great, and the fans are amazing. That's why I keep coming back.

Playing a best of five-set match, you can always bounce back, even if you lose the first set.

When you don't play those big matches for a few years, it's tough to play back-to-back after that.

I never start anything 'I want to be No. 1. I want to win Grand Slam.' For me, no. It's always step by step. The only thing I want to do, it's to push the limit.

I'm always trying to improve, always trying to be at my top, trying to push the limit.

Once you are on court, everything is different. I focus on the match.

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.
