Mr. Haanel put into books the ideas and methods he used to gain his success. Besides the "Master Key System," which he wrote in 1912, he also wrote "Mental Chemistry" and "The New Psychology" By 1933 The Master Key System had sold over 200,000 copies and then seemingly disappeared. The Master Key System is one of the finest studies in self-improvement, mind-stuff, and higher consciousness ever written. Covering everything from how to get wealthy to how to get healthy, Mr. Haanel leaves no stone unturned. With precision, he elucidates on each topic with logic and rigor that not only leaves you feeling good, but also thinking good. The book was banned by the Church in 1933 and has been hidden away for seventy years! Rumor has it that while he was attending Harvard University, Bill Gates discovered and read The Master Key System by Charles F. Haanel.

Basic to his teaching is the correct development and use of mental power -- the key to truly creative power and action, harmony and health, love and happiness, and abundant possibilities. Each part is meant to be studied like a correspondence course lesson, but this is also a book that can be opened at random for whatever gem of advice your eyes happen to fall upon. This age-old wisdom was written by someone who could perceive and tap into Universal Mind but who seems to have no particular allegiance to any specific system of knowledge.
