Unless the problem is not with an unusual preparation regime, but with a cognitive / personality defect. Hyperbolic discounting, moment to moment procrastination in task-switching, and difficulty managing time estimates and proceeding through a preparation process is a trait associated with adult Attention Deficit Disorder. The subject can feel all the guilt and fear in the world about wasting other people's time and looking like an imbecile, without it necessarily adding up to a durably effective scheduling regime. They're constantly checking the clock, and telling themselves "Well, I made it last time, I can spend another 2 minutes in the shower / under the covers / eating breakfast", and establishing a reliable habitual routine that follows a set pace is very difficult for them. It gets especially bad when this trait touches their sleeping habits, leading very often to sleep disorders, in the form of a psychogenic non-24 syndrome from putting off bedtime until they're ready to drop. I find it fairly likely that adult ADD traits, sometimes summarized as 'attentional indiscipline', are linked to modern multitasking (or Internet / gaming addiction, if you like) in the same way nearsightedness is linked to childhood literacy. *Childhood ADHD seems to be a broader category, extended beyond these classic traits into any reason a child might not enthusiastically embrace the American K-12 educational system
