The document provides guidance on how to write an effective diary entry, including that a diary entry should be written from the first person perspective using pronouns like "I", "my", "we", and "our". It should include the date and/or time, describe feelings, events in chronological order, use time-linking words, include location details, write as if the author was present, and be in past tense. The checklist restates these elements that make for a well-written diary entry.
