I am an introvert which in comparison to lots of extroverted people I have known, I have been more willing to do things and be a group player... but mainly when I am comfortable... but hey, played on a rugby team where I knew almost nobody's name.
In a world ruled by extroverts it seems you're a collector of the introverts. 83% all introverted? Are we sure they know what it means, or have I really found the people I can be around without having to actually be around them!?
