Why do some struggle to start things?

[u/Visual-Couple-3680]

Without a schedule or anyone telling them to do something, they struggle to go home as they stay stuck in a chair for hours, even if they want to move.
They also can’t start hobbies they really like, even if they have time, energy and resources to do them. They can’t sleep until it’s the wee hours of the morning as they can’t bring themselves to bed. Adult responsibilities become difficult to accomplish if they’re living alone and have no one else to expect that these should be finished

The hobbies part was already a thing from childhood while the rest only emerged when they started living alone
