Compounding works best when contribution discipline survives boring months. Core idea: Most people understand compounding as a chart. Fewer understand it as a behavioral system that rewards consistency more than excitement. Why it matters: That matters because wealth building is usually lost through interruptions, not through a lack of spreadsheet knowledge. In real life: A modest monthly contribution that survives rough quarters often beats ambitious plans that keep resetting. Common slip: The common mistake is waiting for the perfect market mood before contributing. Try this: If you had to teach this without jargon, what would you tell someone to monitor first? That is usually where the edge is: not in the vocabulary, but in the structure underneath it.
