This is the first all-nighter I'm pulling of what is hopefully my last year of my PhD. I've been spending the past week getting all of my stuff finished up, and tomorrow is the day that I'm planning to start working intensively on the dissertation to the exclusion of all of my other random projects. I'm religious about arbitrary, self-imposed deadlines, so I'm pulling an all-nighter to clear my plate before dawn.
I think I've said this before, but all-nighters are not as fun without genetically modified apples from 7-11, stale bagels, and a sunny yellow dining hall to work in. I keep getting up to get lukewarm coffee and then realize I have to make it myself and then sigh and sit back down.
