For so long people have just taken what I do for granted. It is not easy to do year-in, year-out, to win Grand Slams and be No. 1.
I don't know how I do it, I really don't.
People know me. I'm not going to produce any cartwheels out there. I'm not going to belong on Comedy Central. I'll always be a tennis player, not a celebrity.
When you retire you want to get as far away as possible from the game for a couple of years.
You kind of live and die by the serve.
Golfers are forever working on mechanics. My tennis swing hasn't changed in 10 years.
