『The Greatest Salesman in the World』要約

The Greatest Salesman in the World by Og Mandino is a slim 1968 motivational parable that frames its self-help lessons inside a biblical story. The narrative follows Hafid, a camel boy in ancient Bethlehem who is given ten ancient scrolls by his wealthy master, Pathros, after proving himself through a single determined sale. Each scroll contains a principle for success and is meant to be read three times daily for thirty days before moving to the next, a practice the book presents as the key to transforming habit into character. The ten scrolls form the book's distinctive framework. They include "I will form good habits and become their slave," which opens with the famous instruction to greet each day with love in my heart; "I will persist until I succeed," illustrated by the story of a bull that refuses to leave a burning arena; "I am nature's greatest miracle"; "I will live this day as if it is my last"; and "Today I will be master of my emotions." Later scrolls cover laughter, multiplying one's worth, acting now, and praying for guidance, ending with the promise that "I will act now." The final scroll, "I will pray for guidance," closes the set. Beyond Hafid's story, the book includes a modern frame: a sales manager named Simonides who discovers the scrolls and shares them. Mandino, a former insurance salesman, wrote the book after personal and financial failures, and it became a long-running bestseller. Its central argument is that persistence and repeated positive self-suggestion, rather than innate talent, produce sales success and personal change.
