Good take heed doth surely speed.

Careful attention and prudent caution are likely to bring a successful result. The saying commends noticing risks, details, and consequences before acting rather than relying on haste or luck.

Here, “speed” means to prosper or succeed, not to move quickly. The proverb therefore links diligence of mind with favorable progress, suggesting that foresight helps an undertaking go well.

Use it to encourage someone to check plans, warnings, or practical details before proceeding. Its older grammatical form gives it a deliberately proverbial, archaic tone, so a modern paraphrase may suit ordinary conversation.
