Why gratitude journaling works: the one bad review
Nine people liked it, one was lukewarm, and only the lukewarm one stuck. That asymmetry is the whole reason gratitude journaling works.
A gratitude affirmation is only as good as the thing it points at. "I am grateful for everything" is a slogan; "I am grateful that someone made me tea without being asked" is a memory you can still find in a year. These thirty are written to be finished — most of them leave you a blank to fill.

Finish the sentence. Most of these are deliberately unfinished — "I am grateful for one specific thing that happened today" is a prompt wearing an affirmation's clothes, and the value is in the noun you put at the end of it.
Say one in the morning if you like. Write one at night. The difference matters more than it sounds: repetition sets what you are looking for, and writing leaves you something to find again.
Categories are forgettable. "My family" is true every day, which is exactly why it stops registering. "My brother rang for no reason" happened once, has a picture attached, and will still mean something next year.
The 2003 experiment that most gratitude research traces back to had people list things — actual items, weekly — rather than hold a general attitude. The 2010 review that followed treats gratitude as something closer to a noticing habit than a mood.
A 2021 meta-analysis put the effect of gratitude interventions on depression and anxiety symptoms at small. That is worth saying plainly, because most pages like this one imply otherwise. The practice is cheap, quick and slightly helpful. It is not a treatment, and repeating a line about abundance will not pay a bill.
What it does reliably do is move the noticing earlier. After a couple of weeks you start catching good moments mid-afternoon, because some part of you knows it will want three of them later.
Why gratitude journaling works is the longer version of the argument above. The peak-end rule explains why the end of the day is the cheapest place to put this. If you want a question instead of a statement, try the beginner prompt set, and morning affirmations covers the case where you would rather start the day than review it.

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.
