Memory edits itself every time you replay it. Write the big days down while they’re still accurate.

Each time you recall something you rewrite it slightly, smoothing details and bending them toward the story you now tell. By the tenth retelling it is a good story and no longer an accurate record. Writing it down early is the only way to keep the version that actually happened.

Write half a page about something important from this month, with the details and the names in it. Do it while it is still boring and specific rather than polished.
