Best career options for somebody without a degree

Obviously everybody on the OT has at least 2 bachelor degrees and a masters... But the hard reality is not everybody is an OT baller. Trash does exist and we all know it's a lot harder to find a solid middle class career in 2014 than it was 20-30 years ago.

Here is my situation: Like probably a million other kids every year I went off to college and had just a little bit too much fun and didn't make it to class as often as I should have. Lost my funding and the plan was to work for a year and save money and pay my own way back to school. As often happens in life, a few curveballs were thrown my way. Ended up with a truck note, rent payment and all the other bills that go along with adulthood (electric, water, insurance, cell phone) and 3 years later I'm still working the same service job I got when I moved back home. I've plateaued here and the only possible way to move up would be partial ownership, which likely isn't happening anytime soon. I make enough to cover the bills, but not much else. Definitely not enough for any school.

Financial help from parents isn't an option. Grandparents are all dead.

Anybody have any suggestions on how to better myself? How hard is it to get work on an oil rig? I'm open to moving anywhere and starting completely over.

TL;DR - answer the question in the title. Going back to school isn't option for now, neither is help from parents.
