The theory of Dunbar's Number states that 150 is the number of individuals with whom any one person can maintain stable relationships.
In other words, you will probably not be able to remember the names or faces of people outside that circle of 150.
In Dunbar’s research, he mentioned that the 150 people are made up of:
- 5 intimate friends
- 15 good friends (including the 5 intimate friends)
- 50 friends (including the 5 intimate friends and 15 good friends)
- 150 acquaintances (all-encompassing)
Question for you - How well do you listen and take care of those 5 intimate friends. People don't care about how much you know until they know about how much you care.
