Drawing Lessons from Experience is the good habit of a man to think deeply and reflect upon his experience of relevant situations from the past which are stored in his memory. The Prudent man is continually engaged and thoughtful about what he is experiencing and seeks to systematically learn, building a reservoir of experience to draw upon in the future. 

The opposing vice is to be Hasty/Negligent, a bad habit by which a man jumps to conclusions without diligently considering what his experience from the past might have told him. The Hasty/Negligent man often makes stupid decisions which cause him and others unnecessary suffering and doom him to return to face escalating problems which he could have avoided.
