i was going to mention human resources/personnel also. career counseling would be another field.
i was a psych major in college but never graduated. i ended up going into graphic design and i find it really beneficial as it helps me get into the client's head to design something they will like. of course one has to also have artistic skills to be a designer. i'm now going back to school to finish my undergraduate degree, but not in psych, and may go on to get a mft which specializes in art therapy. i'm planning on getting a masters in yet another field but may do the mft/art therapy eventually too. yeesh, i have too many interests and will be in school til i'm 80!
