Don't be scared of following the obvious path - it won't be anything like what you expect anyway :)

I'd say you should finish what you started; I have a few friends who went all the way through primary school, high school, uni, then with like 4 subjects or one semester to go said "screw this, I've had it". It seems silly to me to spend 15 years studying and get so close to completing a degree, then giving up with six months to go.
