You kind of live and die by the serve.

I'm maybe not quite as sharp as I used to be.

Players aren't quite as intimidated by my name.

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.

When you come back strong, you are going to have little nagging things that you can usually play through, but every now and again, it is to the point where you can't play.

Retirement is a work in progress. I try to figure out my day, and what I know about myself is that I need structure.

In tennis, you can make a couple of mistakes and still win. Not in golf.
