I need to clarify what I think is a terrible transgression against Napoleon Hill.

Everywhere, the word "mastermind" is use to describe a "Master Mind". Let me take a moment to make a point about "Master Mind" and "mastermind" to clear up the proper use of the terms. If you look up the words "master" and "mind" separately, you will understand why Napoleon Hill never used the word "mastermind" in any of his writings....
