1 Never boast about tomorrow. You don't know what will happen between now and then.
2 Let other people praise you — even strangers; never do it yourself.
3 The weight of stone and sand is nothing compared to the trouble that stupidity can cause.
4 Anger is cruel and destructive, but it is nothing compared to jealousy.
5 Better to correct someone openly than to let him think you don't care for him at all.
6 Friends mean well, even when they hurt you. But when an enemy puts an arm round your shoulder — watch out!
