I'm a biology major/psychology minor on the premed track, but I've taken four creative writing courses in the past. I'm in my fifth one at the moment, and I'm taking another one in the spring semester.
It's something I've always been interested in (obviously, I'm on this site), but it's not something I'd want as a career. You don't have to pursue an English or creative writing degree in order to take creative writing classes. Everyone needs elective hours
