Novak Djokovic

I'm a happy man, because I am successful in what I do, of course; but what makes me most happy is I have people around me that I love and who love me back. This, for me, is the most important thing. Nobody likes to be alone.

As a kid, I always idolized entrepreneurs. I thought they were cool people in the way that I thought basketball players were cool people. It's cool that some people get paid to dunk basketballs, but I'm not one of those people.

I was a very focused kid. I always had this crazy lifestyle... billions of jobs, two hours of gymnastics every day, handball, anything with a ball, really. I must have had ADHD or something. I was very energetic, and very small. I didn't start growing until the last year of high school.

As England manager I always felt we needed an extra man in midfield to retain the ball, but that was more as an attacking ploy to help create opportunities. It came from my experience playing international football in a 4-4-2 and spending half my time chasing the ball.
