No more bitching about work. It's not your passion and everyone knows it. You and M have scheduled an end date for it. Yeah, it's not tomorrow, but it's a place.
In the meantime, don't waste your energy complaining about what can't be changed. Instead make a plan to make the situation yours: excel where you can (without taking on too much) and enjoy the breaks you've earned (reading, bike rides, journaling). Be happy that your co-workers are pretty marvelous and that the bike trail and libraries are so close. Be THRILLED that forecasters are already calling for a snowy winter = lunchtime cross country skiing opportunities!
