That the unconscious is powerful and one must respect its power is a truth I never tire repeating since not doing so risks distress and worse.
Another truth is that childhood experiences, during which the basic psychological (ego) capacities governing behavior and thinking develop, is the bedrock of adult behavior. Consider: when angered by a careless driver or phone representative and you later behave impatiently with your spouse or child, is it really they that bothered you or had the earlier experience triggered a memory with that feeling being displaced into the present.
The important lesson being not that one's behavior can be unconsciously motivated, as is that of all people, but that by observing and investigating our feelings we gain greater control over our unconscious strivings and (hopefully) avoid serious errors of behavior.
