Too kool for school, but nowhere else to go
mping: It seems to me that you are experience that "lostness" sensation every teenager feels. I reiterate zaidf's advice. Take a year off or so, travel the world, enjoy your life. Having 18 is a great time to travel or do other stuff that you probably won't have the guts to do again.In due time, you will probably feel the need to come back to get an education. Just don't let the education completely out of your life, in my experience having a degree is great both personally (you acquire alot of skills, meet interesting people, etc) and professionally (I would almost always prefer the guy with a good CS major AND some programming experience  over the guy with 10+ years programming but no CS major).
