The concept of the Mastermind group was formally introduced by Napoleon Hill in the early 1900s in his timeless classic Think & Grow Rich.
He wrote about the Mastermind principle as the coordination of knowledge and effort of two or more people who work toward a definite purpose in the spirit of harmony.
This was also echo’ed by Einstein who proclaimed “You will never overcome any problem, whilst using the same level of thinking, as that which caused it” And further developed by the World Famous Carnegie.
