Interesting. Of psychotherapy models I suspect there is no end and, like drugs, they can be addictive. When I was working with this stuff back in the stone-age it seemed to me that what one had to find was the one that was the better fit for oneself, settle for better rather than keep seeking the best - and just use and adapt. So say at the time Sheldon Kopp might have been life-transforming for me but to my colleagues it was "who? why? really!"
