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.

You can't just buy the sports section of 'The New York Times.' You take the whole paper.

I say it all the time: Texas high school football. It's no joke. It's a big deal. And when you get good coaches like I had at Lake Travis, and then you play other good programs, it develops you very quickly, and it gets you going.

If I waited for inspiration every time I sat down to write a song I probably would be a plumber today.

I've been playing semi-professional football since I was 14, really.
