Six Weeks of Tracking My Afternoon Focus

For six weeks I kept a sheet of paper on the corner of my desk and scored every afternoon work block from one to five. One meant I read the same paragraph four times and gave up. Five meant an hour passed without me reaching for my phone. Alongside the score I wrote three things: hours slept, whether lunch was real food or a packet of something, and how many meetings sat before 2pm.

I started because I kept blaming the wrong things. Some days I was sharp after six hours of sleep; other days I was useless after eight. The log was a way to stop guessing, and it cost me about forty seconds a day.

The log format

Five columns, one row per afternoon block. Date, sleep hours, meal note, meeting count before 2pm, and the focus score. Nothing else. No mood tracking, no long reflections, because I have abandoned every system that asked me to write paragraphs at the end of a working day.

Three patterns that held up

• Context switches before 2pm mattered more than anything else I recorded. On days with three or more separate meetings or handovers, my afternoon score averaged around two. On days with none, it sat near four.
• Sleep showed up, but only below a threshold. Under six hours, scores dropped almost every time. Between six and eight, the difference was hard to see.
• Heavy lunches cost me the first block after eating, not the whole afternoon. By 3pm the effect had usually faded.

Two things I thought I saw

Coffee looked like a clear win for the first two weeks, then the pattern vanished once I counted the days I had slept badly. I was drinking more coffee on those days, not focusing better because of it. The other one was willpower. I was sure I could push through a scattered morning by deciding to try harder. The scores say otherwise: the mornings with four context switches produced bad afternoons regardless of how determined I felt walking into them.

What I changed afterwards

I now protect the two hours before lunch where I can, and I stopped scheduling short calls in that window. It is a small change and it is not a system. The log is still on my desk, mostly because I like having something to check when a bad week makes me think everything has fallen apart.
