I guess having no idea what you want to do and then going to school to figure it out is not the best idea. Any arts degree you get is most likely not going to land you a job when you're done. If you wanted that then making math and science work for you would have been a good idea.
I spent ALOT of money on education, way too much. I have 2 bachelors degrees and they are completely unrelated. The first one was agriculture (pretty easy to get a job actually) and the second one was music. Sure I made the mistake of doing the agriculture degree but it still works for me. I just ended my summer contract and have a nice fat bank account. Now I get to spend the winter playing music! BUT... that arts degree does nothing for me unless I market myself. I have a very successfull string quartet that I started. If I wasn't pushing it and marketing it my arts degree would be an expensive piece of paper on the wall.
