I can improve it a little bit. But it's my head, it's the way I am. So at the end of the day, I will be who I am and I will win how much I can win.

But normally when you talk to yourself [on court] you say; 'I love you, you're a good guy, but don't miss next time, okay.'

Never give up. Last year I was trying to give up but I couldn't.

Many say that (Pete) Sampras is the greatest player. But I say with all due respect to the rest, that he (Roger Federer) is the most complete player in the world so far.

No matter what happens, tennis is still tennis: You can see a lot of great matches, a lot of new people.

There's a lot of things in life that we don't know why they're coming exactly at this moment.

I've felt it (shoulder soreness) since the first day I came, but more so now. Yesterday in the doubles I felt like I couldn't serve at all. I had a lot of pain. I decided to stop because without the serve it doesn't make any sense. It's better to stop and try to recover. If you play, you play 100 percent, not to suffer on the court...Hopefully I'll be ready for the Australian Open. I'll ask for a late start and try to recover. I can playing forehand, backhand, anything except serve.
