If you are going to suggest seeing someone, my zip is 37043. I wouldn't mind traveling to Nashville for therapy. While you may find a number of NLP practitioners or a number of Ericksonian hypnotists, there are few who have mastered both. So, here s what I suggest. Do either or both and your chances of qualifying and making some money on the tour will be greatly enhanced.
Hypnosis is the best way to go.
It is easier to learn anything in a hypnotic state, be it to play the piano, golf, polo, control pain, be more confident or to concentrate. If you consult a hypnotist, no more than two sessions would be necessary. This information would be used to develop a script for the second, audiotaped, session. Finally, in the first session, preliminary hypnosis, without suggestions for concentration, would be conducted. Very likely, you would have already learned to concentrate better after the taped session.
