Not winning at Wimbledon is not going to bother me forever.
If I don't practice the way I should, then I won't play the way that I know I can.
I have seriously thought about retiring, but that was on a good day. On a bad day I've thought about killing myself.
My serve and my forehand I pretty much always had, but my backhand was a made backhand. I worked on it for years.
You have to focus on the process. You cannot be glued to the results.
It's very nice to see when somebody who wanted to work hard and is willing to put the work in gets rewarded for it.
