Most of the time after the US Open, it is kind of like you are trying to finish strong. But to do it five years and maybe six is something that has never been done before, so it is a huge challenge.

What I've done in the game is always going to stick, no matter what happens.

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 still feel like my game is very dangerous. I always will have my serve.

Once the fifth set comes, it's a matter of nerves.

I want to end my career on my terms, not on what people think I should do.

I made it look so easy on court all those years. No one realized how hard I had to work. No one realized how much I had to put into it. They underestimated my intensity.
