I was first introduced to MasterMind 2006 and started to organize my own Mastermind with my Mentor 2008. I still use to go back to Origin = Napoleon Hill and use his reasearch and extended investigations as a tool.
To make a Copy of a Copy is not the Best 2018. We go back to Origin and learn by the Masters Directly. We use the Mastermind Principle and know our results get so much better Together.
