Decisiveness is courage disciplined by evidence.

Acting without evidence is recklessness, and gathering evidence without ever acting is avoidance. Decisiveness lives between them: the nerve to move, kept honest by an actual look at what you know. It is a discipline rather than a temperament, which means it can be practiced.

For a pending choice, write down what the evidence genuinely supports and where you are filling gaps with hope or fear. Then act on the supported part. If you find you have no evidence at all, the next step is not courage but investigation.
