Your voice shakes, say it anyway. The room needed somebody to go first.

Courage is not the absence of the shake, it is speaking through it. A room usually holds several people who agree and are each waiting for somebody else to go first, which is why the first voice matters more than the best-phrased one. Nothing important gets said well on the first attempt. It only has to get said.

When you are the one who noticed, say it before you feel ready. Keep it short and let it come out imperfect. Someone in that room will follow, and they needed you to move first.
