This is a wonderful example of the power of words.  Not only do we undervalue others with the word JUST, we undervalue ourselves.  Sometimes we truly believe we have no power or influence, sometimes it is misguided humility.  But this is a powerful lesson.  I am not JUST anything.  I am who and what I am and will act in all ways possible to improve myself and the world around me.  That's the plan...  no JUST needed.
