This does not always turn out to be the case. More times than not in my experience I've witnessed individuals sign up for NLP Trainer Certification in efforts to find that one piece that they felt that they were missing. Even after Trainer Training I've seen quite a few people still walk out feeling as if they don't know what to do when. Based on these experiences that why I was drawn to the Meta-States Model. These days I'm not as big of a proponent as I was in the past given that I've come across other models and research that better explains the questions that I have been asking.
However I will say that given a field that too often the training courses are reduced so significantly so as to practically render competency building a practice that never gets an opportunity to take place. Hall's trainings are a place that I would consider attending. In my dealings with him he has always been forth right and honest. And I do appreciate his constant focus on self actualization. This seems to be a very useful frame that he has set around his work.
