Archaeology was cool while it lasted. I mean really really cool. I got to do all the fun stuff like dig at presidents' houses and work in the Middle East for half a dozen years, but surprisingly, it turns out I'm not nerdy enough to find the solitary, underpaid life of an academic satisfying. Hence, the square desk job.
Plus, I got a free masters degree out of the whole deal.
I'm much more sedate than I used to be and don't feel the same pressure to counteract my introverted tendencies quite as much.
