All right take a word of advice from an old man, my oldest daughter took it and is doing well. She wanted to be an artist, I told her that there are a lot of "starving artist" in the world today and she needed to find something that combined her artistic needs and she could do for a living. She is now a Graphic artist and owns her own company.
What I would recommend is some thing that has been suggested, but you need to expand on it to make a decent living. Photography. You can make a decent buck as a photographer as long as you are not picky about what you are photographing, do the wildlife photography on the side and if you take the right quality shots you will get a break from someone eventually.
