Part of the problem, I believe, is the nature of deadlines I handle as an adult compared to as a student. As a student, the majority of my assignments were due within a week (if not due tomorrow), so it was easy to track that everything was finished. As an adult, everything is either due by EoD (and therefore has no need of being entered in the system) or due six weeks out (I never did develop the work ethic to beat procrastination, even as an A student).
