Dr Steenbarger's approach is simply more effective - solution focused brief therapy (SFBT) is the state of the art in psychology. Besides it is indeed brief - a couple of sessions is enough to have a lasting impact - forget those endless hours required by the traditional psychoanalysis. Intuitively, it is also the approach that seems to be more appealing - focusing on the good points present even in the bleakest of conditions ("you see, I did follow my systems at least once last month - and sure enough it worked as expected; this month i will double my efforts, and reactivate my trading journal, which I had once found to be of enormous help in the religious adherence to my systems") makes more sense than endless brooding over the spilt milk ("this huge loss in November was a real lasting trauma for me and I realize how it blocked my ability to pull the trigger forever; just like the car crash that made me rethink road safety and sell my Volvo and bin my driving license")... see the difference in those two approaches with regard to the ability to move forward?
