Never confuse being quiet with having nothing to say.

Silence gets read as emptiness by people who talk to think. In practice, the quiet person in the room is often the one with the clearest view, precisely because they have been watching rather than performing. Assuming otherwise about others is a common and costly misreading. Assuming it about yourself keeps you contributing less than you could.

If you are the quiet one, choose your moment deliberately rather than waiting to be invited. If you are not, ask the person who has not spoken what they think. The most useful thing in the room is frequently sitting unsaid.
