The Master Key System was written in 1912 and actually served as the platform for Napoleon Hill. He used the Master Key as a basis for the interviews he conducted for over 25 years to formulate that astonishing Think and Grow Rich philosophy and writing.
During his 25 year study Hill met W. Clement Stone and it was Stone who really provided the missing piece for Hill. Stone made Hill rich.
In 1971, I was fresh out of college, and my first job was working for Combined Insurance. I flew to Chicago for training and W. Clement Stone, owner and billionaire, was my trainer.
Stone had written several books at that point, some with Hill, and he gave us all a copy of “Think and Grow Rich”... which led me to the Master Key System.
We’ve used this system and taught it for years. This is no ‘buy this, point, click and get rich’ thing. It requires work, the kind of work that creates change within… and, by extension, change without.
