My wife and I write an annual letter to one another. They are truly magical and they are great to read back, often bringing us to tears and capturing the struggles of raising children, moving continents etc. They unleash memories when read.
We have ten years of them and they are truly amazing and I recommend it as a slightly less involved shared (two way) ritual .
Author here - We do that too! Typically we'll write a letter for the other person for their birthday. It's a much more reflective letter (whereas the daily note is more "what's going on right now"). Great tip.
To be honest, I think of something like this as far more intimate and thoughtful than writing a letter once a day. Sure, they're apples and oranges. But taking the time to write a letter each year forces you to think about the year in an anniversarial lens; the meaningful moments, the memories, the struggles, the victories, the journeys.
I do this as well with my wife of 10 years, although it's not something we agreed upon -- it just ends up happening in lieu of or in addition to a birthday/anniversary/valentine/whatever gift. Agreed on all points.
