t’s the 50th week of the year, which means it’s time once again for the Besties—a celebration of the episodes that educated, amused, and enriched us most in 2025. David highlights ten standout episodes from this year, revisiting the ideas, stories, and lessons that lingered long after the microphones were off. And all of the voices behind those moments return for brief cameos, reflecting on the year that was and looking ahead to what comes next. From Authors in August and a Market Cap Game Show world championship, to character, community, games, and the many ways listeners took concrete steps toward financial freedom, this episode captures the breadth of what Rule Breaker Investing aims to be: thoughtful, optimistic, playful, and practical. A year in review — not ranked, just remembered.

Longtime contributing writer at the Fool, Anders Bylund, joins David on this trip through time to share the what, why, and when of these stocks’ march through the decade. Did we beat the market?

From Diwali’s lights in India to a “spiffy-drop” on Netflix, this Mailbag travels widely and thinks deeply. A listener celebrates the Rule Breaker habit of lighting candles, not fanning flames, while others ask how to “Add Up, Don’t Double Down” in practice, what makes a business cyclical, and how to think about price momentum. Plus, a 67-year-old Fool goes all-in, a Boilermaker misses Investor Island, and a Brit reminds us that some “periods of time” are best left to translation.
