In this episode of The Winning Edge Coach, we break down one of the most powerful yet underused thinking tools in performance psychology: the Inversion Mental Model.

Popularised by Charlie Munger and rooted in Stoic philosophy, inversion flips the way you approach success. Instead of asking “How do I win?”, you ask a far more effective question: “What would cause me to fail?” From there, you eliminate those behaviours entirely.

This short, practical episode walks you through how high performers use inversion to make better decisions, avoid costly mistakes, and protect everything they’re building—whether in business, sport, health, or life.

You’ll learn:

• What the inversion mental model is and why it works
• How Charlie Munger used inversion to guide decision-making
• The Stoic practice of premeditatio malorum and its modern relevance
• How to apply the PreMortem technique (backed by psychologist Gary Klein and Daniel Kahneman)
• A simple 3-step inversion exercise you can use immediately

If you’re serious about improving performance, sharpening your thinking, and avoiding the hidden mistakes that derail progress, this is a tool you’ll come back to again and again.
