I went to a military school, so I'm always talking like 'Yes, sir,' or 'No, ma'am.' I was doing that even before military school, so I've always had it, I guess.

When you think of Peyton Manning, you think 'ambassador.' The game has grown exponentially during his career because of him and what he means to our game, not only as a football player but as a humanitarian.

You have to find something that you want to accomplish, that you want to achieve. You want to drop 15 pounds. You want to be able to run four miles. There has to be some goal that you set for yourself and, after you've reached that goal, you set a new one. You always have to be shooting for something, striving for something.

You can never let anything distract you from your main objective. My only goal is to be great. That's all I want. That's all I ever aspire to be. Greatness is something nobody can ever take away from you, no matter what happens. So I put all my energy and focus into my craft.

Being home alone at night makes me a bit nervous. If I'm at home alone, I have to sleep on the sofa - I can't face going to bed. I'm there with the TV on and all the lights on. I'm not very brave about anything in life. In tennis, yes. In everything else, not very.

I'm honoured to train players that want more from their football than just raising their small wages.

I think having a vision can make someone an influential man. I'm not talking about acting or anything like that, I'm talking about people I admire, whether it's a writer or a musician or a sports figure or a politician, whatever.

Homophobia in male sports is much stronger than in women's sports; the locker room environment is a lot different. It's going to be much more of a brave step, an earthshaking move, for a gay male athlete to come out.
