The missing item can dominate a collection that already contains years of pleasure.

Attention drifts to gaps rather than to what is present. Shelves full of things chosen and enjoyed over many years can be reduced, in your mind, to the one item you do not have, and a pleasure quietly turns into a hunt. Nothing is wrong with wanting the next thing; the trouble starts when the missing one is all you can see. Absence is louder than abundance.

Spend a few minutes with what you already own and handle three pieces you have not looked at properly in years. Notice what drew you to them. Then see whether the gap still matters as much as it did an hour ago.
