When I was 18, 19, I was presented as the 'aw shucks' Nebraska kid who's coming up with a big serve, and then I flipped out a couple of times, and then I was ueber-brat, when I feel like there's parts of both, but I don't think I am either one, if that makes sense.

Well, immediately we announced yesterday or the day before we're building, with my foundation, a youth tennis and learning center in Austin. I'd like to be hands on with that and not see it periodically.

I think it's foolish to think that if you've done something for so long, you can kind of delete it out of your memory bank or delete every emotion attached to it. I knew when I retired what that meant.

My entire career, I've been a worker.

I, as a cricketer, would like to see 100 counties playing top-flight cricket, just like tennis and football. If I am alive to see that, I will be very happy.

I started wrestling at ten. I played a lot of other sports: soccer, football. I really enjoyed skiing. But wrestling just took off for me. It seemed to be the sport I had an affinity for; I liked the individual, combative nature. There's something special about that. It took me all the places I wanted to go.

When there were no kids to play football with in my local park, I would go to my grandma's factory. She used to give me £2 if I cleaned all the threads and scraps off the floor. I even learned how to sew."

You need to be a professional - how you train, how you eat, how you sleep, where you go outside of football.
