have you considered the military? some branches you can enlist up until 39 years old. if you're physically in shape, or relatively in shape, no medical problems, no major criminal history, and have a high school degree, you should be qualified to enlist. but only a recruiter can clear you.
the military has hundreds of jobs that aren't all combat or infantry related. plenty can find similar work back in the civilian world when your service is done. you'll get paid training, experience, chance for travel, and other benefits. it's only four years long too, so it isn't forever. they have jobs in IT, mechanics, logistics, healthcare, ATC, and others. you maybe surprised what they have to offer.
then, if you still wish to, you can go to college when you're done, and the GI Bill will help pay for it. but, plenty of companies will take years of relevant job experience over someone with just a college degree, and no work experience. especially since a lot of jobs are veteran friendly now.
the military lifestyle isn't for everyone, but it can be to help give you a path towards a career. either in the service or not. do some research, then see a recruiter for more info.
