Bright sparks know when to shut up.

There are these hidden people that attend meetings. They say nothing. You can attend ten meetings in a row and never hear them say a word. Their words are a privilege reserved for the royal family. You find yourself dying to know what they would say. They act as a fly on the wall. With every meeting, they get smarter, by saying nothing at all.

They observe the loud beasts, rather than become a beast.
