I did an English minor while doing my undergraduate physics degree. It's a good thing I took the "heavy" course on literary theory last, because it utterly demoralized me. The sheer volume of books in the library devoted to literary criticism is astounding. It outweighs the entire canon of classics by at least two orders of magnitude, and it's almost all self-aggrandizing gibberish. If you could somehow distill all the original and clear ideas in these books down there wouldn't be enough material to fill a pamphlet! Perhaps I was just unlucky in my choice of books and perhaps I had a bad prof, but after that course I couldn't look at someone doing graduate studies in English and not marvel at their tolerance for bullshit.

The most important lesson in writing is that "nobody wants to waste one second more than they have to reading your drivel, so get to the point". I learned this writing physics papers. I had several English profs who probably still haven't learned this lesson.
