-Friends will more readily betray you because of envy (see what you have up close).
-People don’t remember your generosity (often it reminds them of their own weakness).
-They become spoiled (entitled).
-Friends know where to strike.
-Emotions like love can blind you to deception, no one believes a friend can strike.
-People more likely to repay injury than benefit, one is a burden, another a pleasure.
-Enemies have more to prove (generosity wins people over), expect nothing/low expectations and get everything (must be in return for ‘dis-empowering’ themselves), value gap.
-Honesty rarely strengthens a friendship so friends are hard to read.
-Friends limit your power, they are rarely the best person to help you, skill and competence are more important than good feelings.
-Friends get used to your faults and so are less likely to bring them up to you, enemies will point them out in order to hurt you.
-Relationship is based on mutual self interest and nothing more.
-Enemies keep us sharp, use them to learn truths about yourself, use them to practice fighting.
-Enemies help you frame things as a struggle of good against evil.
