This work investigates the psychological traits and behavioral patterns that distinguish high-performing sales professionals from their less effective counterparts. The authors, David Mayer and Herbert Greenberg, utilize their background in industrial psychology to analyze the personality structures necessary for success in competitive sales environments. They argue that specific psychological attributes, rather than mere training or experience, are the primary determinants of sales efficacy.

This text is regarded as a foundational study in the application of industrial psychology to the field of sales management. The analysis provides a clinical look at the personality dynamics that influence performance in high-pressure commercial roles.
