"This is my third time in five years. 'In general, the main reason I
keep coming back here is because of St. Jude Children's Research Hospital.
I've visited the kids before, and it's a wonderful, amazing experience. And
it's a great opportunity to be in front of my fans again."
"Who knows if I'll come back. That's why I would like not to make a
retirement announcement. You never know. I would not come back unless I feel
100 percent, whether it's mentally or physically. All those factors have to
come together for me to come back. I don't want to come back and play
half-effort (tennis)."
"Tennis is a huge part of my life, it has been and always will be. But
there are obviously other interests I'm pursuing, and there are still a lot
of other things that I would like to experience."
