A degree is generally just a piece of paper that says that you've taken enough courses and done well enough in them to get that degree. Why is it important? If I was running a company, the MINIMUM requirement would be that someone be able to get that degree. If you cannot do that, I don't want you in my company. That degree doesn't tell me that you're actually capable of doing what that degrees claims you're capable of doing. All it tells me, is that you did what you had to do to get it, and that is a bare minimum. If you are in fact intelligent, then what's stopping you from getting that piece of paper that a lot of quite stupid people can get?

High school teachers realize this, and furthermore, many of them see college as this mythically wonderful place of higher learning that would make the ancient greeks jizz their pants. A lot of your high school teachers really would like that for you. College CAN be that place, and that time, however, you cannot wait for a professor to make it so. Community college, Ivy league, or anything in between, college is the place where you ought to take responsibility for your own education. For example, you're taking a linear algebra course, and you find that for the sake of time, your professor is omitting the study of eigenvectors. Does that mean that you yourself ought not study the material, on top of what is required for the class? That depends on what you want from college. If it's that piece of paper that tells society "I'm at least above this level of idiocy", then yes. If you want to come out of college quite learned and feel it was an intellectually satisfying experience, then no, depending on what your actual abilities are.

To answer your question, yes college worth it. It makes you more mobile within society to have a degree, and it's the best opportunity to learn as much as you'd like, with the caveat that you have to be proactive in getting that learning. Can't wait for a professor to spoonfeed it to you.
