Hey p0t8o!
I go back an forth in my desire to do things. Sometimes I fell like things are completly useless, other times I do not. All my parents really seem to care about is me doing something that would support myself, and thus get me out of their life. And as the last child at home, I can't blame them.
While my future is uncertain, there are certain things I do know for sure; I don't want to be working in some dumb dead end job. I did that for almost a year and hated it. In three years you could have a degree and get a decent paying job. Although it wouldn't be where you would want to be, it would be a start. You need credits in uni, that's a certainty. You only need to please yourself in life, not the expectations of others. No sense in doing something you don't want to do.
I think you're a smart guy. Contemplating why we do what we do shows profound thinking. There are those who do what they're told, and those who question the system. Only the later get anywhere in life. You might want to check out philosophy. You should sign up for a class if it's offered, I think you'll enjoy it. It's different than any other class you will ever take and I guarantee it'll give you a different perspective on things. It may even give you some direction in life.
Some advice:
-Stay away from computer careers. Besides the fact it's no longer a desirable market, it's really not a field that will enhance your mind.
-Don't settle for something you don't want to be doing.
-The time will pass no matter what you do.
-Try new things all the time. That's the best cure for apathy.
I don't know what I want to do yet either, but I'll take all the time I need to make a decision. Good luck with your search.
