Any praise goes to my coaches and my teammates. I have the easy part of waking up and going to the gym. They're the ones that have to break my bad habits and teach me new things. They're literally my everything. In my personal life, it's my wife, and in my professional life, it's my coaches and my teammates.

There was a long time in my professional life that I was not happy, and there was nothing anyone else could have done to make me happy. There was a big stretch where I was very sick, and I was very hurt. Those charged with taking care of my health and well-being weren't very good at their jobs. Or maybe they were too good at their jobs.

I'm a goal-oriented person, and instead of focusing on the past, I'd rather focus on the future.

I think, at some point in my wrestling career, I took myself way too seriously, and I took the wrestling business way too seriously. It probably helped sour me on the whole process. It probably helped burn me out.

I can remember running around at the age of 3, wanting to play golf, cricket and football. I was always active, one way or another, driving my parents mad.

I got a job as a football development manager which meant I could coach the students and work with the sports sciences department, all the people in university sector.

You can't just buy the sports section of 'The New York Times.' You take the whole paper.

I did realise more than ever, after the stabbing, that tennis is a business - a tough business.
