In a commercial sense, by ‘selling’ we mean disposing of or exchanging commodities for profit.

Of late years, however, ‘selling’ has taken on another meaning. We are learning to recognize that nearly all human relations involve gaining attention, arousing interest, using persuasion. These are fundamental terms understood in the world of commercial salesmanship. The fact that they have been taken over into other phases of life besides those of commerce, indicates that the human mind is growing and broadening. We are beginning to realize that the act of living itself, in all its varied relationships, is, in reality, a vast business of selling and salesmanship.
