Train your weaknesses before circumstances discover them for you.

Weaknesses do not go unnoticed forever. Either you find them on your own terms and work on them quietly, or events find them at the worst possible time and expose them publicly. The choice is not whether they get discovered but who does the discovering.

Name the thing you avoid: the skill you route around, the conversation type you dodge, the part of the work you always hand to someone else. Give it a small amount of deliberate attention this week, in a setting where failing costs nothing. It is far easier to be bad at something on purpose than by accident.
