Self-control in speech is a mark of wisdom. The fool vents every thought and emotion immediately — there is no filter, no patience, no consideration of timing or effect. The wise person holds back, considers the moment, and chooses words carefully. James echoes this exactly: 'be swift to hear, slow to speak, slow to wrath' (James 1:19).
Memory phrase: Think before you speak.
Talk about it: Why is it wise to think before saying everything you feel?
Prayer: God, help me think before I speak.
