Grieve: Circle of competence requires honest self-assessment of expertise boundaries
Kyle Grieve
“The circle of competence mental model, famously used by Warren Buffett and Charlie Munger, centers on understanding what you truly know and where you have an edge over others. It requires honest vulnerability about where you lack understanding. The model has four key aspects: defining what it is, identifying it in yourself, expanding and maintaining it, and operating outside it when necessary.”

Luca Ferrari
