You are holding in your hands a book by Joe Vitale dedicated to the sales and marketing methods of the world's greatest showman, a true genius and an unrivaled master of money making, Phineas Taylor Barnum. In his activities, Barnum successfully used methods actively used in modern advertising and marketing. Skillfully manipulating rumors, he played on human curiosity, earning huge profits from this. There was even a psychological phenomenon named after Barnum (the Barnum effect), which is partially manifested in people's belief in astrology and palmistry. Barnum's principles are simple, effective and immortal; and Vitale proves that they are quite applicable in the activities of modern companies. The indisputable advantage of this book is that it is very interestingly written, full of interesting stories from the life of the “king of swindles,” as Barnum was called during his lifetime, as well as useful tips and ideas not only for business, but also for personal life. The book is a must read anyone interested in advertising and marketing issues; everyone who wants to succeed in their business.
