Designing a Mastermind Group

In his book Peak, Anders Ericcson talks about developing expertise (tho he focuses on “expert performance”) in unregulated, if you will, artistic or professional disciplines. He cites traditions such as the violin, piano, and chess, as being highly standardized and regulated – it is well documented how to inculcate expertise in those fields.
 
He cites Ben Franklin’s entrepreneurship in newspaper publishing as an example of a professional cultivating business expertise with no formal roadmap or education in the field. 
 
One of the systems Franklin devised to counteract his lack of professional training, according to Ericcson, was the mastermind group concept which Franklin believed should be diverse. 
 
To be a fly on the wall in the Junto Club, wow.
 
So the entrepreneur’s ability  to connect with fellow experts may contribute to the power of an unregulated profession.
 
Regulated proserv consultants have the freedom to sign up for Toastmasters and other groups, but do they have the entrepreneurial foresight, creativity, and drive to imagine what their particular mastermind should look like, and then form it, find it, join it, etc.
 
Ben Franklin though the mastermind should be comprised of a diverse range of experts, so a marketing mastermind group should not be limited to marketers. Which means it’s not really a marketing mastermind.
 
Who comprises the mastermind that is best for you?
 

Addendum: The MasterMind Questions of Benjamin Franklin

Franklin’s mastermind, the Junto Club, lasted for 38 years. He devised the following question to structure meetings.
