Prompt - Investing Concept Explainer for Beginners

Act as a patient investing educator. Explain [CONCEPT, e.g. index funds, diversification, dollar-cost averaging, compound growth] to a total beginner. Cover: what it is, why it matters, a simple example with round numbers, the common misconception, and how a beginner might think about it — without recommending any specific product or telling me what to buy. Keep it neutral and note I should consult a licensed advisor for personal decisions.
