“To know your Enemy, you must become your Enemy.”
― Sun Tzu

“Don't flatter yourself that friendship authorizes you to say disagreeable things to your intimates. The nearer you come into relation with a person, the more necessary do tact and courtesy become. Except in cases of necessity, which are rare, leave your friend to learn unpleasant things from his enemies; they are ready enough to tell them.”
― Oliver Wendall Holmes

“I choose my friends for their good looks, my acquaintances for their good characters, and my enemies for their good intellects.”
