Choose a format you will use
A plain notebook, a few loose sheets or a simple digital document can all hold your notes. Pick the format that is easy to reach and comfortable to use. A beautiful notebook is optional; a convenient one is often more practical.
You might write a sentence about the day, record a question or make a list of things to remember. Your notes do not have to form a complete story, and you do not need to write for an imagined audience.
Use a small prompt when it helps
If the blank page feels uninviting, try a concrete prompt: what did I notice today, what is taking up space in my mind, or what would I like to remember? You can answer in a few words or leave the question for another day.
Some people prefer sketches, lists or dates beside a photograph. The format can change as your needs change. There is no requirement to review every entry or draw a lesson from it.
Think about privacy
Decide where the notebook belongs and who can access it. For digital notes, consider the settings of the service you use. You are free to keep, discard or stop writing notes at any time; consistency is not a test you have to pass.
