The Greatest Salesman in the World
by Og Mandino
Mandino's 1968 parable of a camel boy who inherits ten scrolls of wisdom, each to be read three times a day for thirty days: form good habits, greet each day with love, persist until you succeed, act now. The book is devotional in tone and the scroll practice is the point. Many salespeople have read the scrolls for years.
Read it if…
you want a daily reading practice with a short, repeated text.
Skip it if…
you want a modern, secular approach; this is old-fashioned and earnest.
Three things you will actually use
- Read each scroll for thirty days; do not rush.
- Act now; the scrolls return to this often.
- Greet the day with love; it is a chosen habit.
Do this first
Read scroll one three times a day for the next thirty days before moving on.
Our verdict
Earnest and repetitive by design; the practice works for those who keep it.
