Transformational Processing is not a rote system. It is a framework intended to inspire you to perform creative acts that will again inspire your clients to change. What matters is the positive results that take place. The best of intentions, the greatest amount of energy spent on trying, the best possible explanations for why it didn't work - none of that will help anybody unless you actually help somebody. What helps somebody is that they are being helped.
Different people get widely different results with the same techniques.
That is not puzzling, it just shows that it isn't the techniques themselves getting the results. The variable is the person using the technique. TPS training is intended to put a great many tools in your hand, point you in the right direction, and inspire you to go get great results. And you WILL, once you add to this your own inspired energy and your own intentions.
