One of the meetings that I look forward every 2 months is that of our 3-person Book Club. We spend about 90 minutes discussing books or articles that we have read. Since all of us come from very different backgrounds and have very different reading habits, there is always a lot to learn from listening and sharing. There is no business discussion – because we have very little in common there. So, one can be very open in the talk.
In the 7+ years that we have been meeting, I have found my Book Club meetings to be rich in opening my mind to different mental models and streams of thinking which I would not have ordinarily gotten exposed to. (And I hope I have done the same to my two friends.)
I think all of us should create our own small ‘circles’ where the group meets and shares ideas or readings on different topics. I am sure you will find it stimulating.
