Have you ever had a disagreement with someone to the point where you felt they were your enemy? Maybe someone really wronged you. Maybe they did something so horrible that you could never be around them on purpose again.
How can the statement "Enemies can be useful." be true? What use is someone you find so awful? Well, if you think about it, in order for someone to become your enemy, you must have cared about them at one point. Are you aware that the opposite of love is not hate? The opposite of love is indifference. If you are harboring intense negative feelings about someone it is probably because they disappointed you in some deep way.
To make the best "use" of an enemy ask yourself if anyone you know fits this category. Explore what it is about this person that makes you feel this way. What did they do that hurt you so deeply? What does this experience with this person tell you about you and what you need from people you allow into your life in the future? Even bad experiences can be good for us if we know how to "use" them.
