The 3 pm Decision
Insight
Sleep is largely decided before dinner. The extra afternoon coffee, the skipped walk, the sugar hit at the desk — the 11 pm version of you is simply living with what the 3 pm version ordered.
Why it works
Sleep quality is the downstream product of the afternoon: caffeine timing, light, movement and stress load all register that night. Framing 3 pm as sleep's starting line makes the levers visible.
Practical takeaway
For one week, treat mid-afternoon as the beginning of tonight's sleep. Make one aligned choice daily — the earlier last coffee, the ten-minute walk, the lighter load on the evening.
Good question to ask someone
What did you do at 3 pm yesterday that your 11 pm self paid for?
