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.

It is very hard for me to switch from clay to grass.

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

I'm different than another person who wants to lay back and do nothing for rest of the life and talk nonsense on ESPN... I will not do that. I want to achieve something else.

It's like love. When you look too hard, you don't find it. When you let it happen naturally, it comes.

If I was the type of person who had tennis, tennis, tennis all the time and I went to bed and ended up dreaming about tennis, I would go nuts.

You have to wake up and you have to run if you want to survive.
