In short, vagueness is a destination-less walk.
  It's that in actuality.
  Everything we ascribe BEYOND the act of physically walking
  without a destination, is metaphorical.
  [it could even be said that destination itself is entirely
  metaphorical: DESTINY.

  Ancient Greeks believed in the Fates. They passed it on to the
  Latins.

  So, to not have a destination, is to not have an determined
  Fate. Amazing how the ancient Greek way of thinking lives on in
  the 21st century.
