Why can't I rest even when nothing is due?

Because rest has been redefined as an input, and you can feel the difference even if you cannot name it.

Recovery is for the sake of the next sprint. Sleep is optimised. The holiday is protected because you will come back sharper. Every one of these is defensible and all of them convert rest into a component of work — which means it can be done badly, which means it can be one more thing you are failing at.

Han thinks something specific is lost here: the capacity for deep boredom, the undirected attention out of which anything genuinely new comes. A mind that is always being applied to something never idles, and idling is not the absence of thought but the condition for a certain kind of it. What replaces it is stimulation — different from work, but no more restful, because it is still attention pointed at something.

The tell is what happens in an unplanned empty hour. If it produces low-grade unease rather than relief, rest has become a task with no completion criteria, which is the worst kind.

None of this is fixed by scheduling rest more carefully. Scheduling it more carefully is the disease presenting as its own cure.
