I have ANGST, because for some reason, I always mistake the maximum amount of pages for an assignment I have to do for the minimum amount.
Just today, up until a few hours ago I thought I had to do at least 8 pages of an assignment on philosophers in the Enlightenment era. After I looked at the paper in my notebook with the outline of the assignment, I saw that it only had to be 6 pages, with 8 being the maximum.
I'm quite glad I realize this before I finish, because if I didn't, I'd feel annoyed that I could've done less work in less time and not have points taken off for it being too short.
