Superb condition, lightly age worn only. Tad James utilizes NLP (Neuro-Linguistic Programming) to eliminate irritating behaviors or issues. The Time Line theory is that you go back to the first time you remember a particular problem, do change work, and if necessary go to subsequent times when your behavior or response, was a problem and then do additional change work to resolve it. A good addition to any therapist's library or to anyone interested in behavioral change. (phi)
