Long ago a psychiatrist friend made an important statement: that the unconscious is powerful and one must respect its power. Yet, because of this power, one is often unaware of its influence over poor decisions involving relationships, jobs, and life itself. To defend against the power of the unconscious, as the impulse to engage in a particular behavior at that moment, resist the urge! While not making a decision is also a decision, avoiding poor ones should be the goal. Thus, think rather than act. Road rage behavior is a common example of destructive impulsivity as is suicide of which a well-worn statement is that it reflects a permanent solution to a temporary situation.
Deciding on the choice of therapist is more complex since virtually all therapists are friendly but therapy is a a business relationship and not a friendship. If, over a period of time, one has not gained greater insight into one's behavior and greater enjoyment in life the choice of therapist should be questioned. Which is not to say that change through therapy is rapid or painless but its goal IS change: to gain greater control over the unconscious forces affecting one's life and, ultimately, greater enjoyment.
