Same experience here; while attempting to isolate the factors that made for low days in order to avoid them, I instead experienced a significant increase in low days-- probably because I had to actually assess my mood.

A neutral mood, open to becoming either "good" or "bad" if not closely inspected, would invariably be categorized as "bad", and once labelled, remain that way for the rest of the day (or into the next day/sleep if recorded at night).

I've found stepping back every month or so to reflect on positive things is helpful, but doing anything with too much granularity has only encouraged self depreciating and neurotic thoughts.
