People who really struggle with time management and planning, yup. The lack of an ability to reason about time - to, fundamentally, exercise executive function - leads to these problems where the time estimates are always short.

For some people, it's hard to see all the pieces ("take a shower, brush teeth, put on clothes, pack your bag, take the elevator...) that go into one larger task ("getting to work") and reason about them. It's fundamentally a working memory/executive function deficit.

It's also shocking to me how every intent of leaving well and truly earlier than I thought can also fall apart. The lack of adrenaline in such situations allows a million distractions to creep in. "Oh, I can spend a few minutes to fix my makeup". "Oh, I haven't watered the plants in a while!" I can try to wall some of them off (I will NOT use the computer or look at my phone), but there's real limits.
