When you're going through tough moments, you never know when you're going to have good moments.

A great tennis career is something that a 15-year-old normally doesn't have. I hope my example helps other teens believe they can accomplish things they never thought possible.

My main goal is to stay healthy because when you're injured you realise how lucky you are to have your health.

There's not many firsts in my career, as I have been a part of many tournaments and fortunate enough to win many.

I never played sports or got into the whole guy camaraderie of, like, 'I love you, man! Seniors forever!' So suddenly being in the military with these guys who were under these very heightened circumstances, isolated from their families, living this very kind of Greek lifestyle, it changed my life in a really big way.

I'm a writer. I'm moonlighting on television. I never made any pretensions to that. As much as I like being on 'Real Sports,' I have been a writer since I was a little boy, and that's still my first love.

Football doesn't do sentiment well; it's a cruel profession.

I started playing football young, and my career was on the pitch.
