This volume brings together a comprehensive repertoire of professional influencing skills which should serve the practical needs of managers, leaders, professionals and salespeople. This book is aimed at those who: are concerned about influencing the behaviour of employees who may be better qualified than yourself in a rapidly changing, information-driven world; need to sell high-cost services to an increasingly discerning customer or client base; and want to build and maintain the commitment of others to your goals. Written in jargon-free English, the book brings together the results of a total of more than 130 years of psychological research in how to persuade others to do as you wish. Whatever the problem, if the reader needs the enthusiastic compliance of others to get results, this book shows how. It gives simple instructions for subtle skills, and should make every reader a leader.
