if you don't want to attend a university or state college, maybe try community college. if you can live at home, you'll save a lot getting a two year degree then you would at a four year school. and there are hundreds of jobs you can do with just a two year degree. you still take college level classes, but they are often less intense than a four year school. look on google for jobs in demand with a two year degree, what the outlook and income is like.
have you considered the military? they have hundreds of jobs that aren't all combat or infantry related. plenty can find similar jobs in the civilian life when your service is done. it's only four years long, though some jobs require six year contract. they have jobs from air traffic control, IT, health care, logistics, intel / analysts, vehicle maintenance, trade jobs like construction, electrician, plumbing, hvac, and more. you get paid training for these jobs, and some may earn education towards an associates degree in their related fields as well.
you still need to pass the ASVAB to join, which is standard high school knowledge. and depending on your line scores depend on what job you get. so keep an open mind on what they offer. some jobs require security clearances or other factors to qualify. a recruiter will have more info on the job selection process.
military life style isn't for everyone either. working long shifts, sometimes 12 hours or even more. working days, nights, weekends and holidays. you can be in the US or overseas, and you don't always get to choose your location as well.
