I came to realize that all subjects are related and you can do your "own" thing in any subject. For example, when studying History and having to take English courses, I could write about history subjects that interested me, give a historical slant to things. I had to take a Shakespeare course to qualify as my "citizenship" course (???? :-) so I wrote a paper questioning how what I was studying and a particular Shakespeare play's characters we were studying was germane?

Pick what interests you most and works best with your goals and schedule, etc. and then bend the subject matter to help you learn about yourself and your goals and both the subject matter of the course and that of your main interest. I attended an online university for a degree and had to write papers in all courses, including math and science, computers, etc. Everything contributes/is related to everything else. Find connections.
