Image: The Jaw of Ingratitude. Knowing what would happen if you put a finger in the mouth of a lion, you would stay clear of it. With friends you will have no such caution, and if you hire them, they will eat you alive with Ingratitude.

Authority: Know how to use enemies for your own profit. You must learn to grab a sword not by its blade, which would cut you, but by the handle, which allows you to defend yourself. The wise man profits more from his enemies than a fool from his friends.
