"He who touches tar will be soiled; he who associates with an arrogant man will become like him. Do not carry too heavy a load; do not make friends with someone stronger and richer than you. Why put the earthen pot near the iron one? One will bang the other and break it. The rich man does wrong and is unconcerned; the poor man is insulted and apologizes. The rich man uses you as long as you are useful to him; when you have nothing left he deserts you. He will stay with you as long as you have something; he will drain you without a second thought."
