My theory is that I'm just closer to the sun than everyone else. I weigh more than everyone else, I'm taller than everyone else. When it's really humid and hot outside it's going to take a bigger toll on me.

It's very important to be rested.

The hardest part about traveling for work is that I'm a big guy, so traveling is sometimes uncomfortable for me.

People think when you're struggling and not winning matches it's because you're not working hard. That's the biggest misnomer in tennis.

Everything has gone pretty fluidly in my personal life, so I think that certainly helps.

If someone had told me at fourteen that I'd be six-ten, I might have stuck with basketball, in all seriousness.

There are a lot of things that go on between the lines of a tennis court, mentally, physically and whatnot.

I've done a good job putting some meat on my bones since my freshman year of college. It's taken a lot of work. I was just under 200 pounds my freshman year; I was 6'8' and 198 pounds.

I try not to make a habit of spending the whole year losing in the first rounds of events, but tennis is one of those sports where nothing is guaranteed.

You know, Slams are tough. It's the most physical, in my opinion. You're playing three out of five.

I always knew that my best tennis was going to be in my late 20s.

The best part about traveling for work is that it's better than sitting behind a desk!

A big upper body is not a great thing for tennis, and for me, flexibility is important.

When I left college, I just thought I could play tennis to delay getting a regular job and go there and try to make ends meet. But it's been a very different experience for me, fortunately.

Taking care of my body and my health is my full-time job.

A lot of players have had it worse than me. Look at a guy like Andy Roddick, incredible Hall of Fame player, but he ran up against Roger so many times in big finals.

Davis Cup is a completely different animal.

I have a coach and I have a chiropractor, who works to keep me healthy. I pay their salaries. I pay for their flights as we travel around the world on a weekly basis, and I pay for their hotels and meals while we're on tour.

Tennis is a funny sport.

A lot of times when I'm confident and relaxed on the court, I'm going to be a pretty tough out. But when I'm not so confident and not so relaxed, I tense up and my balls fall short and everything. It just sort of unravels.

When I fly overseas, I usually fly business class. If not, my knees are going to be at my chin.

I've played with Prince racquets my entire career.

What I most look forward to about traveling to MEMPHIS is the great food.

In the past, I've played where I only just rely on my serve.

My family and friends, they know that I'm a really good competitor.

Probably the most infamous story in our family: My oldest brother took a U-lock bike lock and locked my head to the bedpost. And he didn't just do this for a minute or two; he did this for a couple hours. I was maybe 8 or 9, and he was maybe 15.

Any time you get to come to New York and be near New York City, that is a very cool opportunity.

We never got much in the way of material things, but if you can be spoiled by good cooking, my mom spoiled me three times a day all my life.

Our biggest events are the Grand Slams and are always going to be the Grand Slams.

I try not to eat too much, but I always get hungry before a match. I make sure I have enough fuel in my body. I'll eat pasta and a little bit of protein usually. I'm pretty much eating a full meal.

Outdoor tennis plays into my strengths a little better.

There is so much that goes in to being a good tennis player. It's not just what you can do well on the court, it's between the ears as well.

I love building a team around me, and being able to support a group of people is one of the best feelings I've come to know during my career; I imagine this is what a lot of business owners can relate to this.

It's awesome to have the crowd on your side.

In a tiebreaker, you generally have a lot of adrenaline running through. It's all about just holding your serve, trying to hold two serves at a time, trying to stay ahead in the tiebreaker, constantly put pressure on my opponent.

I know where I'm ranked, but I don't look at it that much, I don't study it that much. You really can't look at it that way, you've got to try to win as many matches as you can, and it's cliche, but you've got to take it one at a time.

I'd love to have Trump come watch me. That would be awesome.

The best thing about being 6'9'' is that it helps with my tennis game, especially with my serve.

My marriage and my career are my two top priorities.

My favorite tournament is the U.S. Open because the atmosphere is great.

You cannot just play tournament after tournament like maybe I did when I was 23, 24 years old.

I had no idea I was going to be this tall. Had I known that, I honestly would have stuck to basketball.

Prior to our daughter being born, I think getting married is another big step. That definitely settles things down personally.

I was always a late bloomer.

In any match, making a lot of first serves is very important, especially for me.

Everyone works so hard on their game and on their body. Most of the time, it comes down to who is more relaxed mentally; on the court while playing and off the court.

I'm not really focused on my ranking.

I try to bring a lot of water on the plane with me and eat a really good meal.

There's a lot of times I'll just play too passive and since I'm not going to play defense as well as most guys can, I can't get away with passive play.

For the most part I consider myself a mentally strong player.
