George Horace Lorimer is best known as the editor of The Saturday Evening Post, where he was credited with promoting and discovering authors like Jack London.
Lorimer compiled his life advice into the fictional letters from John "Old Gorgon" Graham to his son Pierrepont. John Graham is a Chicago-based pork and finance baron. In the letters Pierrepont receives advice for his different stages of life.
Old Gorgon's advice is packed throughout the book, easy to understand, and still rings true today.
