I know a lot of people without college degrees and they are some of the smartest people I know.
Graduating college is great and all, but that doesn't mean you're smart. It means you're good at the subjects you took and were able to pass them. But unless one of your courses was "life lessons" or "common sense", that degree won't get you but so far in life. You may get that big, fancy job, but you might not be smart enough to even keep it.
