You can visit the old you through photos and songs. Just don’t move back in.

Old photos and old songs put you back in a version of yourself very efficiently, and that is worth doing on purpose. The trouble starts when a visit turns into an address. Spend enough afternoons in the version of you from four years ago and you start measuring the present against a past you have edited, which is a comparison nothing real can win. Visiting is warm; living there is expensive.

So give it a container: one playlist, half an hour, a specific evening. Then put it down and do something that will become a memory later.
