Do you want an education or not? Are you happy with your current career, or want something else? NOT everyone has a "college experience." Not everyone needs or wants it, either. IF you decide you want to study, you might check out your local community college, see what they offer, & whether of their offerings interest you.
You are NOT going to be a freshman moving into the dorms with 18 & 19 y.o. fresh high school grads, if that's what you mean by "college experience."
