The wise man should restrain his senses like the crane and accomplish his purpose with due knowledge of his place, time and ability.
A wise man should not divulge the formula of a medicine which he has well prepared; an act of charity which he has performed; domestic conflicts; private affairs with his wife; poorly prepared food he may have been offered; or slang he may have heard.
Do not reveal what you have thought upon doing, but by wise council keep it secret being determined to carry it into execution.
An egoist can be won over by being respected, a crazy person can be won over by allowing him to behave in an insane manner and a wise person can be won over by truth.
What the wise do in the beginning, fools do in the end.
As the water shapes itself to the vessel that contains it, so a wise man adapts himself to circumstances.
