^In the end, and throughout life, you are your own
  best friend. You are your own worst enemy. You are a little
  piece of
  everybody you have ever known, and they are all a little piece
  of you.
  You can make yourself angry, you can make yourself cry, you can
  make
  yourself happy and make yourself sigh. You can make yourself
  wonder,
  and you can ask yourself why. Be afraid, be very afraid of the
  one you
  call "i".^
