Psychoanalysis gives time to solve complex problems that have no simple or obvious remedies. Consumer Reports surveys of 4000 therapy patients in 1995 and 2005 showed that the longer the therapy, the better the results.
Psychoanalytic therapy dwells on the past, which can't be changed anyway.
Psychoanalysis explores how a person experiences his or her present situation. Understanding the present allows the person to understand the problematic influence of the person's history, as well as the possibility of new experience in the future.
