We don't ordinarily think of sales as one of the "helping professions," but maybe we should. People tell their problems to psychologists and clergymen. They pour out their hearts to their neighborhood bartender. But they tell their troubles to sales professionals, too, so we should develop our "helping profession" skills.
I have often noticed, when a sales pitch is going well, how the conversation resembles what I understand a therapeutic session to be like. That is the way it should be, if the salesperson knows what he or she is doing
