I've probably put up with more criticism than a lot of people out there. At the end of the day, you block out everything, especially with your personal life.

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 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.

That's when you've got to grit your teeth and hang in there and try and find a way to win when you're not playing your best tennis - that's what I can be proud of

Why'd you leave the match, huh?

Grand Slams are different. If you can get through a few matches, the draw opens up and you get confident. You just need a little bit of luck early, you get through those opening matches and you never know what could happen.

My video game character is a bit better looking than me, actually. I don't think he has to worry about his hair getting messed up.
