It seemed like such a good idea at the time. I encountered a few papers that had some serious problems (along the lines of "I'm going to need to contact the professor, to find out his policy on this"), and so I contacted the professor, and put them to the end. Contacting the professor was a good idea. Leaving them to the end was a bad idea. Especially because I also picked up late papers, and marked them right before the Problem Papers. I have found that, on average, late papers are also problematic. (You'd think that, considering the fact that they had extra time, that they wouldn't do a rush job.)
I thought my essays weren't going to take too much longer. I hit my stride. I was flying through them. I was brilliant. And then I hit the Problem Pile. It's a good thing that I don't drink.
And now it's 11:33pm, and I'm leading a seminar in the morning (and will have to do the reading in the morning as well), plus I still have to put together an 8-minute presentation on one of my essays, for tomorrow afternoon.
New plan: I take along a couple of books, and write my presentation over lunch. I'm going to bed.
