The thing that exhausts a week is not the work. It is the number of small decisions made while tired, each one costing more than it should because it is made at the point of maximum depletion: what is for dinner, what do I wear, when am I going to do the thing I have been not doing since Tuesday.

Batching tasks is the usual advice and it is second best. Batching decisions is better, because a decision made on Sunday at four in the afternoon costs almost nothing and the same decision made on Wednesday at half past six costs the entire evening.

Five dinners, decided, not cooked

Not batch-cooked. Decided. Write five things on a piece of paper and stick it where you will see it. That is the whole exercise, and it removes the daily negotiation that ends in a delivery app more reliably than any amount of Sunday cooking.

Two rules make it hold. One of the five is something you can make in under fifteen minutes with things that live in the cupboard, because one evening a week will go wrong. And they do not have days attached — five options, not a timetable, so a bad Tuesday does not derail the rest of it.

The one hard thing

Every week contains one task you will otherwise carry around all week without doing: a phone call, a form, a conversation, an appointment to book. It costs almost nothing in minutes and a great deal in ambient dread.

Pick it on Sunday, write it down, and give it a slot on a specific day. Not a to-do list — a slot, in the calendar, at a time when the relevant office is open. The slot is what turns it from an intention into an appointment with yourself that you are mildly embarrassed to miss.

Clothes, once

Not five outfits laid out like a school uniform. Check one thing: does what you intend to wear this week exist, clean, in a state to be worn. The failure is almost never taste. It is a shirt in the wash, a missing tight, a coat still at the dry cleaner, discovered at seven in the morning when nothing can be done.

Two minutes of looking. It is the highest-return item on this list and the one most likely to be skipped.

The diary, out loud

Look at the week and say what is actually in it, to whoever else is affected. Not a family meeting. A minute of: I am out Thursday, you have the thing on Wednesday, nobody is cooking Friday.

Most domestic friction is not about the division of labour, which is a real argument worth having separately. It is about information asymmetry — one person holding the whole schedule in their head and being resented for issuing it in instalments. Saying it once, in advance, removes an entire category of Wednesday.

One thing off the list, permanently

Every week, take something off. Cancel a subscription nobody uses, say no to something you agreed to in a moment of weakness, decide that the thing you have moved forward four times is not going to happen and delete it.

A list that only accumulates becomes a monument. The removal is what keeps the hour honest, and it is the only part of this that gets easier.

What this is not

It is not optimisation and it does not want to become a system. The moment it acquires a template, a set of matching containers or a labelled folder, it has turned into a hobby with a maintenance cost, and the maintenance cost is the thing it was supposed to remove.

An hour. Preferably with something on in the background. If it takes longer than that it has stopped being useful.

If Sunday is not the day

It does not have to be Sunday and for a lot of people it should not be — shift work, a Sunday that is already the busiest day of the week, a household where Sunday evening is the worst hour available. Thursday works. So does Monday morning.

The requirement is only that it is before the week rather than during it, and that it is the same time each week, because the point of the hour is to be the place those decisions go.
