With this ranking system, the more you play, the better off you are.

I may be a step slower than I was before reaching 30, but I'm doing all the right things. I guess there are some guys who would take it easy in the latter part of their careers, but I'm stepping it up.

It is nice to walk out on a court to have it packed.

People watched the Masters. It was a huge event. It was at The Garden. Now that it is over here in Europe, it has lost a little bit of popularity in the States.

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'm enjoying my retirement, enjoying my life. I have two kids and a lot of my time is spent chasing these two animals.

I don`t know why, but I love the dog eat dog nature of tennis. It`s real, it`s brutal and there`s no hiding place - it's like a one to one street fight. I love the intensity that comes with knowing you walk off court either a winner or a loser. It`s daunting but very exciting. There is no one to blame except yourself, no one cares who comes second.
