I feel your pain, freshman year I pulled an all-nighter to write a 12 page term paper the day before it was due, and swore I'd never do it again, too much risk. Ended up doing the exact same thing this last semester. Thank god for a universally heavy emphasis on exam scores
No, see, I pulled an all-nighter for
every single homework, paper, or project that I had due. Always. Every semester. I never went to bed with an assignment finished, I just finished by class time in the morning. I also pulled an all-nighter before every single exam. I was great at working under pressure, and at predicting the exact amount of time needed to finish any given project. The problem with that strategy is that life likes to throw curveballs, like family drama, or illness, or a last-second computer issue, or worse...if you have exactly as much time as is needed, you can't manage the speedbumps.
My new philosophy, adopted during my postbacc, is that it only counts as time management if you could manage to pull it off after an unexpected delay hits. For example, in the past 2yrs I have had to pull only 1 all-nighter, and it was because I was working a fulltime job, a part-time job, and taking 2 evening classes, and then happened to get hit with a stomach bug which ate up 2 full days of my time right before exams. I pulled it off because I was used to performing like that...but this time that was the result AFTER a curveball, not as default.
Sometimes I wish I'd figured all of this out earlier, but then I feel that if I hadn't had 8yrs of constant poor time management training me to kick academic butt after putting myself through the wringer, I'd never have managed that week. I spent 2d sick as a dog (lost ~10lbs in those 2d), then got up, took a quiz, went home, pulled an all-nighter to study, drove to my exam, knocked it out, drove to my work, and powered through a 12hr hospital shift. Sadly, once I was no longer febrile and vomiting, it just felt...normal, because I was so used to studying, working, and test-taking like that.
