The Rule of 72 explained

Compound interest is one of the most powerful (and most misunderstood) forces in investing. In this Back to the Basics episode, we break down what compound interest actually is, why time matters more than most people think, and how even small contributions can snowball into life-changing money.

We also talk through the Rule of 72, why dividends can supercharge compounding, and the mindset shift that happens when you stop treating investing like gambling and start treating it like long-term ownership.

What You Will Learn

• Why starting earlier can beat investing more money later

• How dividends can accelerate compounding over decades

• The Rule of 72 and how to estimate how fast money doubles

• Why long-term investing feels peaceful compared to trading
