I am all for education. I am also all about gainful employment. I think of fields like psychology, education, library sciene...those degrees are great, but you need more to get gainful employment.

Have you researched an advanced degree in art therapy, and whether that really would pay off, job wise? How much you make is meaningless if there aren't any jobs to be had.

I might lean more towards a business advanced degree, as a way to 'marry' your passion for art with gainful employment. Or, maybe something along the lines of occupational therapy. BUT, I haven't ever researched the job market for people with Master's in Art Therapy.
