One. All or nothing days

The plan was eight hours. You start at eleven instead of nine, so the day is already spoiled, so you may as well begin properly tomorrow.

That arithmetic is doing something specific. It converts a partly good day into a completely lost one, and it does it several times a week. Two hours is not a failed eight hours. It is two hours.

There is a report that names the failure mode of the eight hour plan before you get to it. Religion is easy, and whoever overburdens himself in it will not be able to keep going, so do not be extremists. It is said about worship rather than about revision, and the mechanism it describes is the one lesson two described: an overloaded plan is an abandoned plan. It is put as a prediction, not as a fault.

The all or nothing rule always sounds like high standards and always produces less work. That is worth sitting with, because it is the opposite of what it feels like from the inside.
