A fool's bolt is soon shot.

Understand the thought

Meaning in plain English

An impulsive action may be taken before its purpose or consequences have been considered. The quickly released projectile warns against mistaking a fast response for good judgement, without making speed itself foolish.

What the words are saying

The bolt is pictured leaving before the person has given the action enough thought. Once released, the response may be difficult to recall or redirect, which gives the image its warning about haste. A figurative use can concern a sharp reply, an accusation or a decision made while important details remain unclear. The proverb does not prove that a prompt answer is careless or that a slow answer is sound. The useful question is what needs checking before the action and what its likely effects are. It favours an appropriate pause when one would improve the response, rather than hesitation for its own sake.

Everyday example

A volunteer drafts an angry reply to a changed rota, then checks the updated notice and asks for clarification before sending the message.

When to use it

Use it when a response is about to be released before an important detail has been checked.
