Take care how you listen to the voice of the flatterer, who, in return for his little stock, expects to derive from you considerable advantage. If one day you do not comply with his wishes, be imputes to you two hundred defects instead of perfections.
Reveal not every secret you have to a friend, for how can you tell but that friend may hereafter become and enemy. And bring not all mischief you are able to upon an enemy, for he may one day become your friend.
However much you study, you cannot know without action. A donkey laden with books is neither an intellectual nor a wise man. Empty of essence, what learning has he whether upon him is firewood or book?
