There is an old saying that you are the average of the 5 people you hang out with. We are social creatures and we take on the social norms of the group of people we hang around. In mathematical terms this is called regression to the mean – as time passes, objects become more like each other.

I’m a member of Thought Leaders Business School. In this group there is an expectation that you write one book a year. While we celebrate people who write books, it is not, ‘Wow – you wrote a book!’, it’s more, ‘Great – you’ve written your book.’ The difference is slight, but significant and dare I say, quite profound.

What are the social norms of your group?

As always, I’d love your thoughts on this here.
