I feel like when I'm match tough and match hard and played a lot of matches I got that competitive winning spirit going and I can get on some rolls like I did last year. I won San Jose, Indian Wells and made the semifinals in Miami so it can happen for me.

I'm fortunate: I can play as long as I want to play. There's no coach or trainer who is going to say to me that I'm dropped or sacked, it's time to move on. I can play as long as I want to play.

I'm more in that Rafa Nadal high-energy high-octane mold out there. I wear that emotion on the court. That's how I play my best tennis. People either like that or not. And I can't change that: that's who I am on a tennis court.

That's what you do all the hard work for, to play in situations that put your body through gruelling times. If you're not up to it, pull out.

Even when I was No. 1 in the world, I was taking it one match at a time. I never was a player to look too far ahead, the way draws can pan out.

I liked Pat Cash, and I loved Mats Wilander. I went to the Australian Open with my parents, and I used to watch Wilander being cheered on by the Swedish fans, and with his game style being like mine, I drew comparisons with him.

Matches are won and lost so many times in the locker room.
