Literature. At least the literature-courses are the only ones I really enjoy participating in. It's not as hella boring as linguistics and -well- history isn't my thing. If it's yours, choose that one.

But, just so you know, literature-courses aren't all about reading hundreds of pages everyday. You don't necessarily read more than in any other course because you learn a lot about the theory (interpretation, historical background, genres...) -- the "Einführungskurse" with their tutorials are much more strenuous.

I chose "English Linguistics", "Introduction to American/English Literature" and "Introduction to English drama" for my studies. The first two are Einführungskurse (and I have an Einführungskurs for German studies as well, "Neuere Literaturwissenschaft") and they really take my time. The last one is a Proseminar I and I really enjoy it. Laziness prevails!
