From the book – “Think and Grow Rich!
In his world renown book – “Think and Grow Rich!” – Napoleon Hill writes that whenever two or more minds come together for a common purpose an additional “Master Mind” is created.
The true definition from “Think and Grow Rich!” states that the Master Mind may be defined as:
“Coordination of knowledge and effort, in a spirit of harmony between two or more people, for the attainment of a definite purpose.”
