Sleep.

I now proclaim that the depriviation of sleep is the worst kind of depriviation that human being can ever endure, or at least for me.

I went to sleep at 10.50 last night – the earliest in almost half a year. And I still wake up feeling tired. Last night’s lessons were not exactly the most enjoyable again, because I was really in a very bad shape. I think even my project mates were worried by how terrible I looked. The crazy thing was that I almost slept my entire weekend through!

Let me try to challenge my limits by going to sleep at 10 tonight. That is if I even make it home by then.
