I've also gotten tired of the job, which could explain why I suddenly want to do something or be somewhere else. Tired of going into the office on a schedule to do mostly the same job I could have done from home. Tired of having to do most everything myself if I want it done right. Tired of hearing people complain about not having their job handed to them on a silver platter (or that the platter isn't shiny enough, or that it has a speck; oh the horror, the work). Tired of not thinking about what they're doing, or seemingly not caring. It makes me wonder if I'm cut out for this 'team' thing.
I opted for an extra week of vacation (in exchange for no pay, basically) so I'm going to try to schedule something within the next couple of months. Las Vegas and DC, I think.
