In the debut episode of Wealth Building with Fexingo, Lucas and Luna explore the power of long-term compounding through the remarkable story of Grace Groner, a secretary who turned a $180 gift into $7 million. Starting with her astonishing estate, they unpack the mechanics of compound growth, the value of patience, and why index funds changed everything. Using historical returns of the S&P 500 and examples like Berkshire Hathaway's early investors, they show how small, consistent investments grow exponentially over decades. Listeners learn why time in the market beats timing the market, how to calculate doubling periods with the Rule of 72, and what it really means to let winners run. No hype, just the math and mindset every long-term investor needs.
