We play at the world's most beautiful beaches but in the world's most challenging conditions. It is not like you play one match and you go back to air conditioning. We do it all day long.

The first thing I do when I get there—like all of the players on tour—is apply sunscreen. One of the few hazards of the job is the wear-and-tear our skin takes from the sun.

I couldn't be messing around and acting like an 11-year-old if we expected to compete well. I wanted to compete well, because it was great to see the looks in the eyes of men—like, "Wow, I am having a hard time beating this kid."

The exercises helped get the flexibility back in my ankle and also increased my overall flexibility. As I was getting into my 30s, I wanted to do everything I could to improve my longevity.

How much we have to hydrate out here in this kind of heat and humidity. I think the most I have ever taken down in one day of fluids is five gallons - a gallon per match. If we didn't replace our fluids, we would probably keel over and die.

I had four different colors of hats, one of which was pink. I just got on a roll with the pink hat. So what started out as a superstition grew into a tradition and an easy way for my family to find me at tournaments because I am the only one with cojones big enough to wear a pink hat.

I still get excited just attending a final four, because the process is so long, so arduous, so challenging, that when it finally arrives, the adrenaline can't help but take over. I love the sense of accomplishment and camaraderie that the indoor game can engender.
