I achieved what I want to achieve and I want to continue doing something else.

I'm not fighting with myself.

I think it's difficult to be No. 1. 'There's too much attention, too much expectation from other people.

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 frustrating when you want to play but can't. I didn't touch a racket for three weeks and when I started playing again last week, I still felt some pain in my wrist.

It's a pity that the tennis is really going down the drain. Every year it's getting worse and worse and worse. There has to be a radical change, and I hope it will be really soon.

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.
