Seneca wrote that the greatest power is power over yourself. We often picture strength as force, pushing harder, winning louder. The Stoics saw it differently. The person who can stay composed when provoked, who doesn't get yanked around by every irritation, holds a strength that doesn't tire and can't be taken. Anger feels powerful but actually puts you under the other person's control, reacting to their move. Staying steady keeps you your own. This isn't coldness or suppression. It's choosing not to hand your peace to whoever or whatever is trying to take it. On a hard day, your calm is not weakness. It's the strongest thing you've got.

Inspired by the old idea of power over oneself. Written by Ugo Charles.
