sure it is. getting a relevant degree for your desired job helps. but while getting a college degree, getting internships within that field of study is also desirable, as companies these days often require education AND experience. even if the intern job isn't paid, a lot of companies will hire you on full time after you graduate, since it'll be a smooth transition.
if college isn't for you, you can always look into community college. it's less intense, usually, then a four year school, and there are plenty of jobs with good pay you can do with just a two year degree. there are many articles you can search online to find that info.
otherwise, look into the military. as long as you are medically and physically healthy, and have no criminal history, you should be qualified to serve. enlistment service is only four years long for a standard contract, and they have plenty of jobs that aren't infantry or combat related, that can easily translate to the civilian world. if you get promoted to Sergeant, you'll get leadership experience too. then, if you want to go back to college, the GI Bill will help pay for higher education if desired.
you could also look into trade schools as well. some community colleges may also offer training for them. HVAC, electrician, plumbing, carpentry, and others can make decent money after training and apprenticeship.
so do some research on what costs and benefits are for each path and decide. where you live could also factor in job outlook as well. so keep that in mind.
