The Greatest Salesman in the World is a book, written by Og Mandino, that serves as a guide to a philosophy of salesmanship, and success, telling the story of Hafid, a poor camel boy who achieves a life of abundance. The book was first published in 1968, and re-issued in 1983 by Bantam. A hardcover edition was published by Buccaneer Books in June, 1993. In 1970, Success Motivation Institute purchased the rights to produce the audio recording. If Mandino's suggested reading structure is followed, it would take about 10 months to read the book. The instructions are to read Scroll I (Chapter 8) three times a day for thirty days straight. Only after completing the thirty days of reading Scroll I, should you continue to Scroll II (Chapter 9) and so forth through Scroll X (Chapter 17). Source: Wikipedia (en)
