A new address becomes real through the first problem you solve there alone.

A place stays theoretical while everything in it still works. The moment the boiler stops, the key sticks, or the bin day turns out to be wrong, you have to learn the building, find the number, and talk to a neighbour, and after that the address is yours in a way that unpacking never managed. Competence is what converts a location into a home.

If you have moved recently and still feel like a guest, take on one small repair or arrangement instead of waiting to feel settled. The feeling tends to follow the doing rather than arriving before it.
