Start with the scene, a detail and how it feels
Choose a photo. Say what happened, add something the picture cannot show and, if you like, describe how you feel about it now. You do not have to include all three every time.
Step one: choose a specific moment
“What was my day like?” can be a large question. Try a tree in bloom, a half-finished breakfast or the sky on your way home. Pick the photo you have something to say about, not necessarily the best-looking one.
Step two: add something nobody could guess
These are original examples. Borrow the structure without copying the experience.
Breakfast: Left ten minutes early for once. Sat down to finish my coffee instead of drinking it while watching the clock.
A walk: Went back to the bridge. It rained the whole time I was here last month. Today I noticed the tall trees on the other bank.
Dinner: We told the same old stories and laughed at them again. The group photo is a blur. I still want to remember this evening.
Step three: save it and stop
A few sentences do not need to become an essay. You can add a simple tag or associate someone who was there, but organizing should not be a barrier to your first entry.
What if there is nothing to write tomorrow?
Skip a day or keep just a photo. After a few days, revisit an entry and notice which details make you glad you wrote them down. Begin with that kind of detail next time.
