People repeat in adult life emotions they experience in childhood. Many of the people whom I spent the last 30 or 40 years treating at so much per minute wouldn't have needed any treatment at all if they had had the right care as children.
We have come to see that just as the child must learn to love wisely, so he must learn to hate expeditiously, to turn destructive tendencies away from himself toward enemies that actually threaten him rather than toward the friendly and the defenseless, the more usual victims of destructive energy.
