You cannot change me; this is the way I am.

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.

I was making comebacks every single year. That makes it difficult mentally. It causes a lot of stress.

Wimbledon is not the tournament I love. I don't like how they treat the players. There are small things that don't cost them anything and they make such a big deal out of it. If they treat us this way, well, we have to treat them the same. We want to be respected, the way we respect Wimbledon, even if it is not the best Grand Slam on earth.

If you get operated, something can go wrong and you can just say bye-bye to tennis. That's what happened to a lot of soccer players in Europe. They get operated, some things, it's not the mistake of the doctor. It's just some surgeries, they just don't go the right way...My injury will never go away. It's already become so chronic there's no chance to fix it so I can play without pain.

Don't get too excited when I am winning, and don't get too depressed when I am losing. Just keep it cool.

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.'
