The Master Key System is a system that teaches the ultimate principles, causes, effects, and laws that underlie all attainment and success. The results you will attain from using this system are so startling as to appear incredible. For this reason, more and more people are becoming students of The Master Key System than ever before.
The Master Key System was published in 1912, when Haanel was 46 years old. It is written in the form of a course in New Thought, mental development, financial success, and personal health. The book was heavily promoted in the pages of Elizabeth Towne's New Thought magazine The Nautilus. By 1933 it had allegedly sold over 200,000 copies worldwide. Haanel practiced the financial principles he preached, and was a self made success who owned several major companies.
In 1919, Napoleon Hill wrote Haanel a letter thanking him for The Master Key System. In the letter Hill stated, "My present success and the success which has followed my work as President of the Napoleon Hill Institute is due largely to the principles laid down in The Master-Key System."
