"One of the most effective things you can do to build better habits is to join a culture where your desired behaviour is the normal behaviour" (Clear, 2018, p. 117)

Clear discusses the impact of three key groups in this section of the book, the close, the many, and the powerful, and describes the seductive pull of social norms. Consider the statement above and discuss both the positive and negative impacts these three groups may have on a person's success with behaviour change. Pull examples into your discussion, these don't need to be personal but can be if you're comfortable sharing.
