Originally published as a 24-week correspondence course in 1912, Charles Haanel's The Master Key System presents a complete, step-by-step program for achieving the success you most desire — through the precise application of thought and mental law.
This work is rumored to be what inspired Bill Gates to leave Harvard and start Microsoft, and was one of the primary inspirations behind the bestseller The Secret. By 1933, it had sold over 200,000 copies worldwide. Today, it remains one of the most influential personal development texts ever written.
Using precise logic and a consistent framework, Haanel shows you how to feel healthy, think clearly, and attract wealth — not through wishful thinking, but through a systematic training of the mind across 24 progressive lessons.
