Look at things as they are...

Look at things as they are, not as your emotions color them. In strategy, you must see your emotional responses to events as a kind of disease that must be remedied. Fear will make you overestimate the enemy and act too defensively. Anger and impatience will draw you into rash actions that will cut off your options. Overconfidence, particularly as a result of success, will make you go too far. Love and affection will blind you to the treacherous maneuvers of those apparently on your side. Even the subtlest gradations of these emotions can color the way you look at events. The only remedy is to be aware that the pull of emotion is inevitable, to notice it when it is happening, and to compensate for it. When you have success, be extra wary. When you are angry, take no action. When you are fearful, know you are going to exaggerate the dangers you face. War demands the utmost in realism, seeing things as they are. The more you can limit or compensate for your emotional responses, the closer you will come to this ideal. ~ The 33 Strategies of War by Robert Greene
