It's sad to see you leaving, but I did want to make a comment or two on "introvertial qualities" you mentioned.
First of all, introversion isn't a bad thing at all; we're just conditioned to think it's bad, and that extroverts are superior. That's incredibly wrong, and really insulting to introverts. Over a third of people are introverts, barely a minority.
Introversion isn't a disability, it's just a different way to think. There's a marvelous TED talk by Susan Cain
here. Definitely give it a watch.
