Someone who admits a gap in their knowledge is easier to teach than someone pretending to be full.

A teacher, a coach or a manager can only put something where there is room for it. Saying you do not have a piece of this yet opens a space, and the explanation goes straight in. Pretending to be complete leaves nowhere to put anything, so the help bounces off and everyone wastes the afternoon. The admission is not weakness, it is making yourself usable.

Pick the thing you have been faking competence at and tell the right person this week. Name the exact gap: not the whole subject, the particular step. People are almost always more generous with that than you expect.
