My first wife called my an introvert and hermit, but she was wrong.  My doc got it right ten years later when he called me a "Type A personality."  Why the contrast?  As a leader, I like to lead from behind (watch the party of new people from a corner with my nose in a book before I decide who are my friends and how to take over the world; I'm also a dictator by trade).  Actually, several personality tests pegged me as a dictator.  Dictators don't particularly like to lead.  But if you put us in positions of leadership, we will lead with an iron fist.  When I had my own construction crew, I noticed that (as did the crew, duh).  When my wife starts saying, "Yes, Sir!" I know I've taken it too far!  My sister says I think too much.  My coworkers called me "deep" and "deep thinker."  So, I'll create a new word.  That's what dictators like me are.  I like the best of both worlds; perhaps I'm an introextrovert.
