If Marcus Aurelius had been an insurance salesman, he would have written a book like this one.

📚 The Reading Life 📚

The author of today’s book, Og Mandino, was a bomber pilot during WWII who came home and found that he wasn’t able to find a job anywhere.

Eventually, he became an insurance salesman, but while traveling all the time for unpredictable, low sales commissions, he would sit in bars all night and eventually became an alcoholic.

His wife left him, taking their child with her, and he was thinking of committing suicide, until he stumbled into a library one day and discovered the books of W. Clement Stone, Napoleon Hill, and all the other personal development giants of that time.

They basically helped him pull his life out of a nosedive, after which he wrote The Greatest Salesman in the World, which now has millions of copies in print and is universally regarded as one of the greatest sales book of all time.

But it’s so much more than that, and we’re going to explore that today.

Below, I share a short summary of The Greatest Salesman in the World, as well as my best book notes, along with some additional recommended reading.
