The week before the (US Open) I gave a few interviews for CNN, USA Network, New York Times, USA Today and Sports Illustrated which had been arranged beforehand. The reason for giving these interviews is not only because working with the media is just part of the job, it is much more my desire to contribute to the promotion of tennis in the U.S.

Once you reach a good level in tennis it fills you with a lot of motivation. I hope I can do it for a long time.

I'm as patient a father as I am on the tennis court. It takes a lot for me to get really upset, but sometimes kids can get you really cross if they really keep bugging you.

There is no way around the hard work. Embrace it.

My favorite shot is always gonna be the forehand. It used to always be my favorite shot when I was young, so it's the one I've won all the points with.

I'm not the kind of guy who wakes up angry.

When I was 12 years old, I was just horrible. My parents were ashamed to watch my matches. I would play on a court at the local club and they would watch from the balcony. They would scream, 'Be quiet' to me and I would scream back, 'Go and have a drink. Leave me alone.' Then we would drive home in a very quiet car. No one speaking to each other.
