1. Do not brag about tomorrow,because you do not know what another day may bring.
2. Praise should come from another person and not from your own mouth,from a stranger and not from your own lips.
3. A stone is heavy, and sand weighs a lot,but annoyance caused by a stubborn fool is heavier than both.
4. Anger is cruel, and fury is overwhelming,but who can survive jealousy?
5. Open criticism is better than unexpressed love.
