I definitely feel there's room for improvement.

My dad said if you become a tennis professional just make sure you get into the top hundred, because you have to make a little bit of money. You make a living so you can pay your coaching and, you know, your travels.

I always knew I had something special.

Obviously, matches and all that stuff takes its toll on your body and so forth. But as you get sort of a bit older, a bit wiser, and a bit more experienced, you know also how to handle it.

When you do something best in life, you don't really want to give that up - and for me it's tennis.

I think it's very hard for coaches to work with me. They'll no doubt have a good CV afterwards, but at the same time they're under a lot of pressure.

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.
