I don't have to get myself pumped up or calm myself down. As we get into the later rounds of a tournament and there is more at stake, I have even more adrenaline. If we make the finals, it's just an extra opportunity to win a tournament at my age. That doesn't come along that often.

Playing against better competition makes you better and more focused, so you can do what you have to, to win.

When I was on the U.S. men's indoor team, I was on the road 200 days of the year and sometimes in the worst conditions. We didn't have the food or luxuries we wanted. We didn't have a laundry service. So every night after the match, I soaped up my uniform in the shower. I learned to rely on outside things as little as possible, whether it was music or massage. I just got out of the habit of relying on outside things.

The indoor game is much more of a team game, having to work effectively with a group of 15 to 20 people, striving to improve every day, every drill, even every contact. The beach game is much more of an individual game within a team sport, much less about organized practices with coaches and much more about just playing the game.

In high school, some of the guys were really into music. When I first joined the team as a sophomore, I was blown away when we came out for our first home match—I'm getting goose bumps just thinking about it. The seniors would bring their whole stereo system. We started by yelling and stuff inside this little room just off the gym; then the coaches said, "Ready. Go!" We threw open the door and came running out. Even when I hear the songs now I get all jacked up.

My dad was a really intense competitor and that rubbed off on me. He was loud and vocal on the court, so I let him do all the talking. But I developed a kind of quiet intensity that I knew I had to have to improve and compete with grown men. It took every ounce of focus.

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.
