Two in a row!

I won't admit that I'm just now diving into the writing portion of my bibliographic essay. If I were, though, I'd say that the process is driving me up a wall. My other classes this semester are statistics, geography, and software documentation, so essay writing has been non-existent since last semester. This is my first big assignment since beginning tutor training and really thinking about the writing process. I'm finding myself thinking as much about how I'm writing as what I'm writing, and it's kind of distracting. Has anyone else run into this problem, or has my brain just turned into finals mush?
