Sometimes when you're putting the work in it just seems so, so hard, and you never know when that work's going to pay off.
Having been away from competitive tennis for a while, I am looking forward immensely to getting back on the circuit ... I am looking forward to playing the Big Girls. People have had expectations from me even when I was 10 years old. I try to switch off but you are right, it isn't always easy to do that because the expectations are really mounting.
Always staying focused is something that's been very tough for me. I'm still working on it.
I'm focused on going out every day and doing my best.
When you walk on a court, clear your mind of everything unrelated to the goal of playing the match as well as you can.
Ninety percent of my game is mental. It's my concentration that has gotten me this far.
If I were asked to name one aspect of tennis that is the biggest weakness of players of all levels, I would probably say concentration. However good your shots, however fast your movement and reflexes, all is lost if the mind is not controlling every move.
Throughout my career, my mind rarely wandered, and I was never sidetracked by distractions, no matter what I was going through off the court.
I've been around so long that I might be in record books for being the longest, weirdest, most pathetic great player ever. Look t how precocious I am at 33.
In this job it's like beasts of prey in a cage

This [defeat] has taught me a lesson, but I'm not sure what it is.
There is Peter Graf, Steffi's father, with his head on his chin.
He slips . . . but manages to regroup himself.
He's now letting Chang play his own game - and he does that better than anyone.
She [Monica Seles] has so much control of the racket with those double-handed wrists.
It was all right until the sun came out and then everything started getting warmer.
Sure, I've been on the Tube...I caught it to Eastbourne once.
There's no doubt there are issues with clay. Our issues have issues that are issues right now. That's not a secret.
That's one of the best sets I've seen him play, although I should preface that by saying I haven't seen him play before.
I'm not worried about the weekend, I'm worried about Saturday.
Let's hope his nerves will run through his veins.
She [Serena Williams] played some great shots, but so did I, and that was the only difference.
Unbelievable, yet, what else could it be?
You'd have to think that if he'd been around today, Rod Laver would have been Rod Laver.
