How did they get rich

Think and Grow Rich is a self-help book by Napoleon Hill, so it doesn't have characters in the traditional sense. However, it does mention several successful individuals from whom Hill drew inspiration and knowledge. These include Andrew Carnegie, Henry Ford, J.P. Morgan, and John D. Rockefeller. These individuals are not characters, but real-life figures whose success stories and principles are used to illustrate the book's concepts.

"Think and Grow Rich" is a self-help book written by Napoleon Hill in 1937. It was commissioned by businessman Andrew Carnegie who was intrigued by the process of success. The book is based on Hill's interviews with over 500 successful men and women, including Henry Ford, J.P. Morgan, and John D. Rockefeller.

The book outlines 13 principles for success, including desire, faith, specialized knowledge, imagination, organized planning, decision, persistence, the power of the master mind, the mystery of sex transmutation, the subconscious mind, the brain, the sixth sense, and the fear of poverty, criticism, ill health, loss of love, old age, and death.

The central idea of the book is that our thoughts create our reality, and by actively controlling our thoughts, we can control our reality. It's a classic in the personal development genre and has influenced many subsequent books and authors.

In the book Think and Grow Rich, Napoleon Hill presents several principles of success. One specific example is the story of Edwin C. Barnes, who had a burning desire to become a business partner of the great inventor, Thomas Edison. Barnes had no money or resources, only his determination. He took a freight train to Edison's laboratory and presented himself. He started working there, not as a partner but in a minor role. However, he seized his opportunity when Edison's new dictation machine, the Ediphone, was not selling. Barnes saw its potential, convinced Edison to give him a chance, and successfully sold it, eventually becoming Edison's partner. This story illustrates Hill's principle of 'Desire: The Starting Point of All Achievement'.
