Here is my 2 cents:
Oxygen and Norbert seem to be in agreement with me. I am much more interested in what can be done, than "why it is difficult" The topic seems to be counterproductive- potentialy feuling negative beliefs and self fulfilling prophesies.
All of the arts and technologies that make the paraliminals great: NLP, Eriksonian techniques, etc, are built on positive assumptions- ie: solution oriented, goal focussed, generative thinking, finding/developing resources, etc.
Whatever you focus on is what is created- personaly, I want to create easy effective and lasting change.
