If you don't want to practice, unless you have a hard-nosed coach, you don't have to.

The good news is I have time.

There are only four U.S. tournaments that the very best players in the world play every year - Palm Springs, Miami, Cincinnati, and the U.S. Open. So how would golf or NFL or NHL fare if there were only four times a year that their very best were visible? Tennis went international, and for us to expect it to be popular media-wise is very naïve. And that translates into children and families being interested.

Getting to number one in the world without a coach is highly unlikely.

You have to be extreme to be exceptional. I couldn't revel in being number one. I had to get to zero. When my fitness was at its peak, I was intimidating. I made guys cave in. They'd be dejected in the locker room after matches, and I'd go out for a run, as if it wasn't enough. I'd rub it in their faces. I meant to do that.

The first thing I would do is create one office that controlled all of pro tennis so you had one central voice that spoke for tennis. Central governance is something that's really held the sport back and will continue to do so.

The reason I didn't take the baseball route is because they don't have rankings for baseball players.
