Five pieces of wisdom about interpersonal relationships: First, treat acquaintances as strangers to maintain boundaries; the ones who can hurt you the most are acquaintances. Second, treat newcomers as potential threats; humans have no natural enemies, and peers can be enemies. You should first be wary before being kind, so that the kindness later will be appreciated rather than taken for granted. Third, treat all relationships as short-term; every relationship is a value relationship, and no relationship can maintain its value indefinitely. Fourth, regard benefactors as exceptional horses, and see yourself as the one who recognizes their potential. Choose a horse that is faster than you to carry you forward, and life will accelerate. You must groom the horse well and feed it properly. Fifth, treat others as dogs and see yourself as a god. This comparison of dogs and gods is not meant to be derogatory; it is neutral. Most people are unaware that they are domesticated and programmed dogs, and even less aware that they inherently possess spirituality. Managing the relationship between humans and dogs, or the relationship between gods and humans, becomes much simpler.
