Lasst uns auch Feinde sein, meine Freunde! Göttlich – wollen wir wider einander spielen.

—Friedrich Nietzsche

A false alliance is created out of an immediate emotional need. It requires that you give up something essential about yourself and makes it impossible for you to make your own decisions. A true alliance is formed out of mutual self-interest, each side supplying what the other cannot get alone. It does not require you to fuse your own identity with that of a group or pay attention to everyone else’s emotional needs. It allows you autonomy.

—Robert Greene
