The most confident people are comfortable saying “I don’t know.” The insecure ones never can.

Admitting a gap requires feeling secure enough to survive the gap being visible. If your standing depends on seeming to know things, every question turns into a threat and you start manufacturing answers, which is exhausting and eventually obvious to everyone. People who are genuinely sure of themselves can afford ignorance in public. That ease is made of exactly that.

Say it out loud once this week in class or at work, then follow it with a question. Watch how little it costs and how much you learn. Notice who in the room cannot do it.
