I like math. Math is easy. Do X math problems by X date because that's the quiz. It's simple, it makes sense, you know exactly what to do. Statistics is okay, you have a problem and you set aside several hours to do it. English, god fucking damn english. You have this paper due by X date. You have no idea how much effort this paper is going to involve until you're already beyond the point of no return. A poorly timed english paper, done either too early or too late, can completely fuck up your entire schedule by pushing everything else onto the back burner as you scramble to assemble proper sources while that thing you thought of is still fresh in your mind.
