Based on An End of the Year Retrospective by Pat Kua.
Go through your planning tools (e.g. personal and work calendars, to-do lists, journals, etc) and list any events or activities (by month) of significance to you. Capture these as if you were a neutral bystander.
Examples might include: “Moved house”, “Took part in a virtual panel”, or “Read Lord of the Rings for the 2nd time”
