Be slow to promise, but quick to perform.

Commit only after considering whether you can truly meet an obligation. Careful promises protect others from disappointment and protect your word from becoming unreliable.

Once a commitment has been made, act promptly and follow through. The saying joins caution before giving one’s word with diligence in carrying out what has been agreed.

Use this saying when advising someone to avoid casual commitments and to complete accepted responsibilities without needless delay. It suits reminders about dependability, whether the obligation is personal, practical, or professional.
