Most players who play tennis love the game. But I think you also have to respect it. You want to do everything you can in your power to do your best. And for me, I know I get insane guilt if I go home at the end of the day and don't feel I've done everything I can. If I know I could have done something better, I have this uneasy feeling.

When you make the schedule, you're not planning on playing deep into every single week, or at least I haven't in the past. I'm not physically or mentally ready to pick up my bags and go to Monte Carlo. I definitely have to look at what's best for my chances at (at the French Open).

In the States, tennis is sixth or seventh on the totem pole as far as sports go.

I used to, like, hit for a half hour and then go eat Cheetos the rest of the day, come out and drill forehands. Now I'm really trying to make it happen, being professional, really going for it, and I miss my Cheetos.

I got to play in a crowd, play in Wimbledon finals, be the guy on a Davis Cup team for a while. Those are opportunities not a lot of people get.

I'm not the savior of men's tennis in America. I'm just a kid trying to win a few matches.

I used to go to the US Open on my birthdays and sit in the nosebleeds.
