The Master Key System

The Master Key System is a personal development book that was originally published as a correspondence course in 1912. Along with "The Science of Getting Rich", by Wallace D. Wattles, the Master Key System is the source of Rhonda Byrne's inspiration for the book and the film "The Secret".

Rumor has it that while he was attending Harvard University, Bill Gates discovered and read The Master Key System by Charles F. Haanel. It was this book that inspired Bill Gates to drop out of the University and pursue his dream of "a computer on every desktop." You probably know the results. . .

It is Silicon Valley's secret that almost every entrepreneur who made a fortune in recent years did so by studying the words Mr. Haanel penned over eighty years ago! Almost every millionaire and billionaire in the Valley read The Master Key System by Charles F. Haanel. Since this book was no longer in print until recently, copies of The Master Key System became a hot commodity in the Valley.
