You might be happy
About two years ago, I bought a calendar — the kind you hang on the wall that now primarily serves a decorative function. I bought two packages of Post-it type tabs at the craft store. They are about the size of the ones that say “sign here.” One package of blue, and one of green. I wanted to track how many good days (blue) I had over time, and how many genuinely awful days I had over time (green).
