Since the first publication of "The Selling Process" thousands of enthusiastic readers of the book have voluntarily borne witness to its practical, dollars-and-cents value to them in their daily work. Preachers, doctors, lawyers, bank officials, clerks, book-keepers, mechanics, laborers; as well as business executives and sales managers and salesmen—men and women in scores of widely different vocations—unite in testifying to their increased earning power and fuller satisfaction in living and working. They credit these results to their study and continued use of "The Selling Process." The value of that book will be at least doubled by the supplemental reading of "Certain Success." Therefore the two are now published as a set of working tools for any ambitious man or woman who is resolved to earn success.
