Thanks in part to this tennis board, I am playing very very well. I've been thinking that playing good tennis is a state of mind. Confident, loose, athletic base.....ala federer. Notice that the two best players in history sampras and fed both brought a similar state of mind to the court. Arnold Palmer said that when he was playing- his round did not start on the first tee. It didn't even start on the practice range, nor upon arriving at the club. He said his round started when he woke up and got out of bed. He would start to get in the right state of mind. Relaxed! Loose! Federer once told me the best way to improve is, "to have confidence and a good coach". Just thought I would share. Hope this makes sense to everyone!
