wow, a lot of unhappy campers here. Hey elsewhere, long time no see. I hope you can resolve the problem, maybe get involved in something that take you out of your comfort zone and challeges you a bit. Join some groups on meetup.com, it's a blast.
I'm still a carpenter (and I like my job) but I am about to graduate and will be attending graduate school next. Education is a lot of fun, there is so much to learn. Maybe taking some courses can get you out of your rut, it's worth a try.
Take care my friend, I'm sure you will figure things out.
