Do not slight the discourse of the sages, but busy yourself with their maxims; because from them you will learn discipline and how to serve princes.

Do not kindle the coals of sinners, or you may be burned in their flaming fire.
Do not let the insolent bring you to your feet, or they may lie in ambush against your words.
Do not lend to one who is stronger than you; but if you do lend anything, count it as a loss.

Do not go traveling with the reckless, or they will be burdensome to you; for they will act as they please, and through their folly you will perish with them.
Do not pick a fight with the quick-tempered, and do not journey with them through lonely country, because bloodshed means nothing to them, and where no help is at hand, they will strike you down.
Do not consult with fools, for they cannot keep a secret.
In the presence of strangers do nothing that is to be kept secret, for you do not know what they will divulge.
Do not reveal your thoughts to anyone, or you may drive away your happiness.
