Jobs are jobs. I've been a hunting guide, a fishing guide, a whitewater guide, done some logging, built a bunch of custom homes and a bunch of other stuff that has all had it's rewards in experiences. Bottom line, they all were jobs. My best advice....LIVE somewhere you can escape your job and circumstances and DO (for fun) what you love. That's why I live in MT. I may not be rich $$$$-wise, but in experiences I've had a life many envy.
As far as career choices, if I had to do it all again and was as young as you...I'd become a fireman. Lot's of time off...great benefits and pay....rewarding and adventurous work.
Good luck!
