There are tons of careers. Teaching (at a variety of levels), working as a profession in any type of fine art (painting/drawing/writing), Graphic designers, illustrators, game design (video/board/table top rpg), television/movie writing, museum curators/educators. It really does depend on your interests. Find what you like and how you want to use your creative skills.
I studied painting in my undergrad with a minor in art history. To this day I try to continue to work as a painter selling my art, and use my love of art to teach and study art history. I get to use my passion for art to allow it to fill my life in all aspects.
