Being 33 years old and having a net worth of zero, you are WAY ahead of the game! Most people your age have significant negative net worth (owe more than they have in assets).
You may have a worthless degree, but you have a degree. Surprisingly, this matters a lot for office jobs.
The real thing I think you need to determine, is how much do you want to work? Going from zero to a full time lame job at Walmart or an office temp might be too much. You might want to start transitioning into it, working a couple days per week, leaving time for music, etc.
The other thing to think about is how presentable you are. That will determine what sort of work you can do. Do you need a haircut, have visible piercings or tattoos? I'm not saying change any of this, just understand that it will limit your ability to land certain jobs. Jobs that you probably don't want anyways.
When I was in college, more than 20 years ago now, I drove big rigs hauling tomatoes all summer with a lot of guys that spent their winters working at ski resorts. We worked 12 hours a day, 7 days a week from July through October, at which point we were laid off and could collect unemployment. That gave them 10 or so weeks to cruise to the mountains and start working as bartenders or ski lift operators. This usually was only 3 days/week, and they skied the other days. Some ski resorts had bunkhouses for staff to stay in for very low rent. Then the ski resorts closed in April, and they got unemployment for 12 or so weeks until the tomato season started up again in July.
This is just an example, but with a little imagination and mustachianism, you could do something like this and retire for good in 12 years or so. Also, I'm in California, but I'm sure there are similar types of things to do in Florida, Colorado, NY, or wherever you are.
Good luck!
