Occasionally, allow yourself to be a hypocrite. Why? To remind
  yourself that it's there. Otherwise, we can easily fool
  ourselves into believing that we are always consistent, always
  honest, always true to ourselves and to others.* We can become
  blind to our own hypocrisy, while those around us can see our
  hypocrisy quite clearly.* And... by exposing our own hypocrisy
  to ourselves (by willing exposing to others on occasion), we get
  a rare opportunity to begin eliminating it within ourselves by
  learning how to *spot* our own hypocrisy *before* it comes out
  of our mouths, or out of our behaviors. Is it easy?* Probably
  not.* But I suspect learning humility rarely is.* At least this
  way, you can remain somewhat in control of it, growing a shield
  within you against attacks on your character by reducing some of
  the places where you might be arrogant, leaving behind a
  healthier sense of self; a truer self-esteem. -Ken
