Use prompts that pull concrete detail
Questions like "What felt lighter today than yesterday?" or "Who did you think about but not contact?" are more useful than broad prompts that invite generic life summaries.
Switch between body, memory, and people
The strongest journals move between how the body felt, what the day contained, and who shaped it. That is why mixed prompts tend to reveal more than repeating the same emotional question every night.
Keep prompts short enough to answer quickly
A prompt should lower friction, not create another assignment. If it takes too much effort just to decide how to answer, the journaling habit gets brittle.
