Circle of Competence
The first rule of competition is, you are more likely to win if you play where you have an advantage. Doing so requires a firm understanding of what you know and what you don’t know. Your circle of competence is your personal sphere of expertise, the area where your knowledge and skills are concentrated. It’s the domain where you have a deep understanding, where your judgments are reliable, and your decisions are sound.
The size of your circle isn’t as important as knowing the boundaries. The wise person is the one who knows the limits of their knowledge, who can say with confidence, “This falls within my circle,” or “This is outside my area of expertise.”
Operating within your circle of competence is a recipe for confidence and effectiveness. But venturing outside your circle of competence is a recipe for trouble. You’re like a sailor navigating unfamiliar waters without a map, at the mercy of currents and storms you don’t fully understand. This isn’t to say that you should never venture outside your circle. Learning new things, gaining new skills, and mastering new domains is one of the most beautiful things about life.
Celebrate your expertise, but also acknowledge your limitations.
