Mentally, I'm not ever going to go away.

For me, it's important that a fan can buy something that is related to me. Like in soccer, you buy a shirt and it's got somebody's name on the back. That's kind of a cool thing.

Seriously. I'm not playing to prove anything to journalists. I'm playing for myself, for my fans,to make people happy.

I used to get nervous, you know if my parents would come watch. And then I would get nervous if my friends came and watched. Today it's not a problem anymore actually, because now I enjoy it. I see that they, you know, respect me immensely, and I try to put on a good show and show that I can still play very good tennis.

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.

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.

Tennis can be a very frustrating sport. There is no way around the hard work. Embrace it. You have to put in the hours because there is always something you can improve. [Y]ou have to put in a lot of sacrifice and effort for sometimes little reward but you have to know that, if you put in the right effort, the reward will come.
