A circle of competence only protects you if you actively maintain its boundaries through four disciplines: map what you genuinely understand better than competitors, mark the edge where confidence should drop sharply, expand slowly through years of focused work, and honor the boundary by declining competitions that fall outside. The hardest discipline is the last — most failures come not from playing badly, but from entering arenas you cannot win.
