My essay is complete!
My goal was to work through the night and finish by 7am so that I could get in one 3-hour REM cycle of sleep. It’s now 7:30, which is pretty good. I might be able to sleep in until 10:30.
At this point, my only regret is not studying for my exam at 1pm. But I’ll have an hour to glance over the material between noon and 1pm.
