^"--The difference between an observation, viewpoint, belief, &
  opinion

  observation - is the facts that you observe
  viewpoint - is when you attach meaning to those ideas/facts
  belief - is when you "implement" a viewpoint and you are
  "convinced"
  opinion - is a bunch of viewpoints along with beliefs,
  connections, & speculation

  Change the meaning by changing the viewpoint.

  You can test this out by attaching different meaning to ideas,
  then you will eventually get better at attaching the meaning
  that you want to attach."

  (from http://www.mind-programming.com/ - a great website that I
  had forgotten about. Its Giant List of Emotions is especially
  worth looking at - there are things that you never thought of as
  emotions that are, in fact emotions)^
