I don't know, I always get the question 'how do you feel after the game today?' and, of course, if you're winning you feel great and if you lose you don't feel good. I think that's a pretty obvious question.

There's just nothing like playing on Arthur Ashe Stadium. It's truly amazing.

The only one I feel pressure from is myself to go and give my all for every match and, obviously, I'm a competitor.

I don't really spend money like crazy. I buy what I need and what I really want, and if I'm buying expensive things I do think about the purchase many times before I buy it.

One day my dad would say, 'OK, if you want to play tennis I can help you out.' And that's how it started. And I had a goal. I wanted to beat my mom first. And my parents and my brother. And that was the ultimate goal.

I have a really wide range of interests and I've still got time to work out my exact direction.

The fact is I still have quite a few good years in front of me. I still improve.
