^Autotelic - a word you might not have seen but it is a great
  personality trait:

  Many people are "goal driven" - power, comfort, fame, happiness.

  But autotelic people do things for the sake of doing them. They
  get happiness out of everything they do, and are curious about
  everything around them. They are never bored; they don't look to
  the OUTSIDE to find happiness; they have it within with
  everything they do.^
