1. Don't brag about tomorrow. You don't know what a day will bring.
2. Let another person praise you, and not your own mouth. Let someone else praise you, and not your own lips.
3. Stones are heavy. Sand weighs a lot. But letting a foolish person make you angry is a heavier load than both of them.
4. Anger is mean. Great anger overpowers you. But who can face jealousy?
5. Being warned openly is better than being loved in secret.
