Sara Wilson you're so right. But that's why it's SO important to
  do it yourself. Why? Because, like you, I want the world to do
  that. But yet, a good part of the world DOESN'T do that. But
  you're part of the world. I'm part of the world. If WE start
  doing it, maybe bit by bit we can chip away at the hard shells
  and the seeds of gratitude might be planted in others. You may
  never get to hear it - you may never get the full satisfaction
  of the fruits of your labor -- but once you develop an attitude
  of gratitude, it starts to come naturally and you don't care as
  much if others do it, because the feeling you get inside is so
  well worth hanging on to. "
