Learning about art history is great. It's absolutely worth dedicating four years, or even a lifetime, to learning about art. At the same time, it's a really good idea to learn how to feed yourself and pay off the debts that you're accumulating to study art. I learned a couple of trades while I was studying physics. I've spent the last 20 years of my life working in one or the other of those trades. The physics degree was incredibly valuable to me personally. Learning to program a computer on my own time has been useful to me financially. Learning to paint houses kept me in food until I could find work programming. It also led me to other fun activities such as tile setting and laying pavers.
Setting tile might not be very erudite, but it is both financially and personally rewarding. It's also putting that study of art history to practical use, because mosaics are cool, and you don't get to build mosaics unless you're a pretty accomplished tile setter.
