If I had to teach this in one paragraph, I would start here: focusing only on dividend yield can lead you to miss the total-return picture. Core idea: Total return includes capital appreciation. A stock growing earnings and reinvesting at high rates may deliver better long-term income even if today's yield is lower. Why it matters: That matters because the compounding of dividend growth often overtakes a static high-yield position within a decade. In real life: A company yielding 2% but growing dividends at 12% annually will pay more absolute income than a 5% yielder growing at 1% — usually within 7-8 years. Common slip: The mistake is optimizing for today's income and ignoring the trajectory of tomorrow's income. Try this: If you had to teach this without jargon, what would you tell someone to monitor first? The point is not to memorize the label. The point is to know what variable is actually doing the work.
