The peak-end rule: two moments become the whole day
Your memory of today will not be an average of it. Under the peak-end rule two moments do nearly all the work, and one of them is the last one.
A week you never review gets remembered by whatever happened last, which on a Friday is usually an inbox. These twenty-six prompts are a short, unsentimental week review: what you finished, who made it easier, what you can leave until Monday without guilt. Answer three, write two lines each, and stop before it becomes a performance review.
26 entries
Write the finished thing before the unfinished list. Prompt one asks for one completed item, which sounds trivially easy and often is not — a working week leaves you holding a mental list of everything still open, and the completed items make no noise.
Take three prompts and stop. The beginner prompt set is the same idea with a lower floor if you are still finding the habit.
How a week is remembered depends heavily on how it ended. That is the practical argument for a Friday entry: left alone, the closing moment of your week is whatever your phone showed you at 6pm, and a written review puts something specific in that slot instead. Prompts six and twenty-one — the best twenty minutes, and the one moment worth remembering — are the whole mechanism in two questions. The peak-end rule is the longer version of this argument.
Prompt seventeen matters more than it looks. Explicitly deciding that something can wait until Monday is what makes the weekend usable, and it works better in writing than as a resolution.
Writing down what went well is one of the few journaling exercises with a controlled trial behind it. Seligman and colleagues in 2005 tested a three-good-things exercise and reported improved wellbeing in their intervention groups.
There is separate research on the weekend half. Sonnentag and Fritz's 2007 work on recovery from work identified psychological detachment — mentally switching off from work, not merely stopping — as a distinct component of recuperation. That is the case for prompt twenty-three, which asks what you want to leave at work tonight.
A bad week does not need a celebration entry, and forcing one is worse than skipping the page. Prompt twenty-four exists for this: one thing you still got through. Nothing on this site counts streaks, so nothing is broken by a Friday you did not write.
Why gratitude journaling works explains why the finished half of a week is so easy to forget. Saturday prompts pick up where this leaves off, with rest and presence rather than review, and Sunday prompts handle the gentle preparation for the week ahead. Reader stories show what a few months of this looks like in practice.

Nine people liked it, one was lukewarm, and only the lukewarm one stuck. That asymmetry is the whole reason gratitude journaling works.
