What you said pretty accurately described my high school experience. I'm 28 now. After HS I bummed around 2 different colleges over 6 semesters and 4 different majors. I never liked what I was learning very much so eventually I just left because I had a full-time job as a sysadmin that had been doing while attending school.

Since then I've been doing web development at a couple different smaller agencies. Usually either the job is great and the pay sucks or vice versa. That's my experience at least. It sounds pretty ungrateful now that I'm saying it.

Anyway, a couple of moths ago the owners of my company said that they were going to move to out of state and that all (5) of us were going to work from home. At first I resisted, but then I realized that this could be an opportunity. Despite the monotony of working at home, I have been a lot more free to work on my side projects and the MVP for my startup eyeclash is launching this month. I can honestly say that I've never felt better about the work that I am doing.

So I guess my point is, don't expect the way you feel to change with the scenery. College really didn't help me much with my personal aspirations and neither did most of the jobs I've had. Working on my own stuff and collaborating with others on "side projects" (aka possible startups) is really the only thing that has been able to bring me the satisfaction that it sounds like you are looking for.
