Three years here, and I’ve tried the big spreadsheet, the phone widgets, and a paper log on my desk. All useful for about a week, then too much friction.
What stuck is a five-minute Friday note on my phone. Template is three lines: appetite before dinner (1–5), afternoon energy (1–5), and one sentence about what felt easy or forced that week. I don’t log daily.
Last Friday I saw four low-energy afternoons lined up with days I skipped lunch, which was more useful than any single day’s number. I still read the older maintenance-tracking threads and nod, but this is the version I can keep doing on a busy week.
Anyone else have a low-effort review habit that survives real life?
