December 2025 Mailbag: “Am I a Fool?”

It’s the final Rule Breaker Investing podcast of 2025, and the year ends as it always does—with your Mailbag. David shares his annual year-forward market call, then works through listener notes that capture the heart of the Foolish journey. We hear from a father investing alongside his seven-year-old son, an investor who audited his own selling history and discovered just how early he’d stepped off some great rides, and Fools thinking carefully about contribution timing, position sizing, and excellence that keeps winning. Along the way, David revisits core ideas like letting winners run, being a “for” person, and ultimately answers the question that brings the year full circle: How do you know—really know—Am I a Fool?
