I'm going to respond to your post momentarily, but, seeing how its my birthday and I'm feeling mildly entitled to freeform bitching...

Could your signature possibly be any longer? You wrote one of the longest posts I've seen in a while, about a rather deep philosophical subject, yet your signature still managed to be longer than the god damned post...Christ on a crutch!

Anywho, concerning your post...

All things considered, you're really not that bad off. Just the fact that you're wondering what direction your life is headed in is often more important than where you actually go with it. Many of the people I meet around your age are spending large amounts of money on college courses, and they aren't even sure why they're taking them, these people are forging ahead without even knowing where or why. At least you're taking the time to ask.

Contrary to the popular belief of people who watch entirely too much TV and too many movies, not everyone manages to have that moment of clarity where the true path they must take in life is instantly revealed to them.

You might accuse me of oversimplifying, but I believe you'll find what you need if you simply take the time to sit down, or if you prefer, take a long walk and think about what makes you truly happy in life. Not simple, mindless pleasures, but what do you/can you do that you derive true satisfaction from. That should give you a solid indication of where your path lies.
