Mark Zuckerberg was already known to millions worldwide as the Harvard dropout who started the world's largest social network in his tiny dorm room. Today, his persona has expanded to epic proportions as Facebook's IPO has made him the third wealthiest tech entrepreneur in the United States (and among the top 30 richest people in the world, population 7 billion). People who have followed Facebook and Zuckerberg's meteoric rise know that Zuckerberg is an introvert. And he's not one of these closet introverts who looks like an extrovert to anyone who doesn't know it. His introversion is fairly obvious and well-documented. The good news for Zuck (that's his Facebook username, so I trust I can be that cozy) is that introvert sentiment is on the upswing. It's almost hip to be an introvert and to be who you are, in all of your introvert glory. So here are a few "introvert, honor thyself" thoughts for you, Zuck, to consider as the spotlight goes from bright to blinding.
