Well, I don't think that appeasing your parents is necessarily the wrong thing to do. Sometimes we have to go around Robin Hood's barn to get to the path that we feel we should or want to be on. And again, that is not necessarily the wrong way to travel.

I may be wrong in my thinking here, but to me, it seems that having a good degree is always a plus in your pocket and something you may be able to fall back on in the future should the art path not turn out the way you hoped or planned it to. While it may take some time to graduate with the Library degree and put off you putting more time into your art right now, it does have it's benefits.

There is nothing wrong with having your goals of working in the art field. I think it's wonderful. Why not make a conscious decision to continue on the path you are now on while looking further into the field of art at a slower pace. Getting as much information as you can about the art world and what might be available to you while working on your current degree can only be helpful to you when you graduate. It will help to give you better focus on where and how you wish to pursue your dream and a more defined way of achieving it.

Of course, this is purely my opinion and I'm not trying to push anything on you at all. It is completely your decision. I only hope that you give things some good thought. Take your time, there is plenty of time to take!
