That's why I enjoy Davis Cup, and I really enjoyed college tennis. It's very special. You want to go out there and compete your hardest, because you don't want to let anyone down. You want to absolutely give it your all for your team. And that's sort of the mentality I've taken to pro tennis.

Quotes from the same author

To take pressure off myself, I realize how fortunate I am to be playing a sport for a living. If I take that mentality onto the court, there shouldn't be any pressure because I'm already fortunate to do what I do.
 John Isner
As a kid, I was a little self-conscious because I was so much taller than everyone. A bad habit of mine used to be slouching. Eventually, I realized my height was something I couldn't control, so I might as well accept it. I've certainly turned it into a positive, because without my height I probably wouldn't be as good of a tennis player. It's a gift, and I've made something of it.
