Too Busy or ADD?
Why it might be ADHD: People with ADHD have particular trouble with tardiness, due mostly to their distorted sense of time and their inability to shift focus. There's a saying that people with ADHD run on a clock with just two times: "Now" and "not now." When the "now" is filled with something they enjoy, time flies by and they have an extremely hard time pulling themselves away, says Nadeau, who is also the director of the Chesapeake ADHD Center of Maryland. When they're not engaged, time moves excruciatingly slowly, so they go out of their way to avoid boring activities—like waiting.
