The worst study session

Yesterday while on the can I decided on a whim to check my Email, and low and behold I had an assignment due the next day at noon. So, I get to go to the library and study for like 10 hours to write a stupid essay on the great schism. Like why can't I just remember to just study sometimes? Last Saturday I just sat on my butt being bored when I could have worked on stuff then. Anyway I am genuinely in shock at the fact that I was able to write that whole essay and do all the research in one day, I just hope it isn't awful.
