Decisiveness is refusing to make uncertainty more important than progress.

Uncertainty is a permanent condition, not a temporary obstacle, and treating it as something that must be resolved before moving means never moving. Progress is possible alongside not knowing; it just requires accepting that you will be partly wrong and correcting as you go. Giving uncertainty veto power is a decision in itself.

When you feel unready, ask whether you are actually missing something specific or just uncomfortable with the general fog. If it is the fog, act anyway in a way you can adjust. Comfort is not the same as readiness, and waiting for it is expensive.
