I am re-reading this book for the third time and am atually trying to implement the philosophy on court. Has anyone else had success with the IG? I was shocked how many bad thoughts I had about my game while playing on court. I am really trying to correct that. I tried watching my shots impartially and watching the seams of ball to focus. Of course, I was hoping I would suddenly be an amazing player! LOL How long did it take for the ideas to work? I guess it all depends on Self 1 and Self 2, right? Also, has anyone not had success with this philosophy? I have found my stress level go down while on court while trying out the ideas, for sure.
