Nothing sustains motivation better than belonging to the tribe. It transforms a personal quest into a shared one. Previously, you were on your own. Your identity was singular. You are a reader. You are a musician. You are an athlete. When you join a book club or a band or a cycling group, your identity becomes linked to those around you. Growth and change is no longer an individual pursuit. We are readers. We are musicians. We are cyclists. The shared identity begins to reinforce your personal identity. This is why remaining part of a group after achieving a goal is crucial to maintaining your habits.
