I love my job most of the time. Right now it's getting a little tiresome but between the beginning of October and now I've had 1 day off. That's the life of an oilfield mechanic though. It's a fun job, challenging though. I'll regularly travel 800km+ each way to sites up the ice roads in Northern B.C. and Alberta for repairs to equipment.
When I graduated high school I got a job with Coca Cola and 2 years in felt the same way you did. I would have stuck with it and kept feeling my life was nothing until they laid my off 3 days before christmas, no joke. I found this job and have never looked back. Looking back I realise that I needed something to push me out of my element to find what I needed and I think you need that too. Maybe if you can handle the cold look to move to Alberta here. We have a serious labour shortage, estimates are 100,000 vacant jobs, and the pay is pretty good. I've helped 5 friends move up here and they all love it.
