>>137Congrats on already having a planning mindset at 19. You're gonna go far.
>driving testWhy are you afraid of failing the driving test? You can take it as many times as it takes. You might have to wait a few days in between, but oh well. If you read the manual you should be fine. If you fail, pay attention to what you did wrong and correct it the next time.
>community collegeCommunity college is a great idea. Just make sure to take it seriously. A lot of people think because it's CC that it's not "real" but it's real college and you're paying real money. As for the debt thing, it's relative. If you were going to attend, say, Stanford University to study computer science and had to take on debt, then hell yeah, do it, you'd pay it off in no time after graduation. On the other hand, if you have to take on debt to go to Podunk State University to study french literature or something... bad idea, most likely.
>be usefulIf you're good with computers you can make great money cleaning out spyware and malware from people's computers. It's tedious and not very interesting, but you can charge, shit, $75 to $100 easy for most jobs. Retail places tend to charge way more, so people will happily pay you.
As far as what to invest your time in... the world is a crazy place right now, the future is uncertain, but one would probably not go wrong studying anything related to computers (computer science, IT, programming, and so on) or health care (nursing, medicine, surgery, physical therapy, etc.). Professionals in such fields are useful and welcome just about everywhere in the world. Ultimately you should choose whatever is fun for you and makes you happy, but those are just some ideas.
