John Isner quotes:

It's just simple: just keep fighting and keep believing, try not to show weakness out there.

I won't be turning into Novak anytime soon.

I was never pegged to be the next great American tennis player by any means. I wasn't a prodigy. I'm a late bloomer. Whatever happens, I'm proud of what I've done.

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.

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.
