Whole-weekend tidy-ups do not last a fortnight. What lasts is the opposite: little time, every day, always in the same zone.
One zone a day
Monday the kitchen drawer, Tuesday the hallway, Wednesday the desk. Small zone, short time, an end in sight. A whole house in two weeks without ever losing a day to it.
The rule of three piles
Keep, go, decide later. The decide-later pile goes into a dated box. Whatever is still in there in three months, unmissed, leaves the house.
Keep things near where they are used
Objects go back if the place is convenient. Keys stay in the hallway not through discipline but because the bowl is there.
Clear surfaces run the rest
Worktop, dining table and bedside table. If those three stay clear, the house looks tidy even with cupboards still to do.
Fifteen minutes at the end of the day
The evening reset is what stops things piling up: dishes away, clothes in the basket, surfaces clear. The next day starts from zero.
