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.

If all manners of labor were forbidden to thee you would fall to your knees and beg an early death.

To learn and master anything, one has to pay the price in time and concentration, until it becomes part of one’s personality and habit in living.

Obstacles are necessary for success because in selling, as in all careers of importance, victory comes only after many struggles and countless defeats.

This is a sequel to Mandino's 1967 bestselling book, published in 1988 and set fourteen years later than the first part; the main character Hafid is in a sad state, mourning the loss of his wife, Lisha.
