The book consists of four parts. In Part I the author has described the psychology of negotiation through which successful men and women sell their way through life with a minimum amount of friction in their relationships with people. Part II has been devoted entirely to the psychology of selling personal services of every kind, with particular emphasis on facts of great value to young men and young women on the threshold of their careers. The third part is a comprehensive analysis of the methods by which one of Americas greatest and richest men, Hery Ford, sold himself from poverty to fame and fortune. Part IV has been devoted to the analysis of a principle which has been responsible for all that is good in our present civilization - the principle which must be understood and applied by every person who hopes to attain and hold any worth-while station in life.
