Yes, I made mistakes by rebelling, by acting out in confused ways.
It doesn't matter whether I qualify or wildcards.
To win Grand Slams you have to be in the right frame of mind, the right physical shape.
I do still have some of the experience from playing, but it's been so long since I've been out in those quarters, semis, finals, the important final matches, just against the top players.
Let me say that the path I did take for a brief period of my life was not of reckless drug use, hurting others, but it was a path of quiet rebellion, of a little experimentation of a darker side of my confusion in a confusing world, lost in the midst of finding my identity.
You have to block everything out and be extremely focused and be relaxed and mellow too.
