Groups largely define how we think of ourselves. There are two main types of groups: primary and secondary.

group — any collection of at least two people who interact with some frequency and who share some sense of aligned identity. primary groups — small, informal groups of people who are closest to us. primary group — the long-term, complex one. meritocracy — a bureaucracy where membership and advancement is based on merit—proven and documented skills.
