Use the fewest useful categories
Broad categories are usually enough.
Do not decant everything
Original packaging may carry useful identification and instructions.
Avoid inventories no one needs
Track only where retrieval or value justifies it.
Visual perfection is optional
An organized home does not need to resemble a store display.
Practical boundary. Measure first, respect product load limits, and do not improvise wall, ceiling or overhead installations when the structure or appropriate hardware is uncertain.
