Every possession consumes some combination of money, space, time, and thought.

Nothing you own is free after purchase. Everything takes some space, some cleaning, some maintenance, some low-level attention, some decision about whether to keep it. Individually these are trivial and collectively they amount to a real ongoing tax on your life that never appears as a bill.

Before acquiring something, count the upkeep as well as the price. And consider removing a few things you already own that are quietly charging you rent in attention.
