Don't go to college if you're not there to learn, expand your worldview, and challenge yourself intellectually. (This isn't meant to sound condescending, but it may. I just mean that college is about the studying and hardcore mastery of a specific subject, which isn't something everyone (most people?) are really that interested in spending time on.)
I never understood why people (and by "people," I usually mean parents) treat college like a trade school. If you're looking for job training there are appropriate places that cost less and will give you much better opportunities in the long run (business schools, computer science schools, trad schools, culinary arts academies, etc.). Universities just really aren't designed to do that and they're certainly not a cure-all or ideal situation for everybody.
"Go to college so you can get a good job" just seems like the biggest lie that kids are force fed on a regular basis that no one seems to be calling them on. (And this is from someone who wants to teach at a college for a living.)
EDIT: But if you don't know what you want to do, community college is an ideal solution as they're great places to kind of find yourself and get a lot of your general education stuff that most places want you to have anyway out of the way.
I think this is some of the best advice in the thread, especially the last big. College does not equal a guaranteed "good job" anymore. If you aren't wholeheartedly in it, get out or switch, because you're getting yourself into a LOT (and I do mean a lot) of debt for no reason.
As someone who graduated about a year and a half ago (and it took me 8 months to find work) you really don't want to meander around trying to figure life out, going through the motions and accumulating massive debt. At the same time, you don't want to transfer schools too much, because you'll lose a lot of credits (and money) by doing that.
But I do agree that community college is the best way to go if you're still figuring out a path, and frankly, even if you're not. It's a lot cheaper, you get a lot of Gen Eds out of the way, and it gives you time to breathe.
