You find an old note: ‘Option 2, but only if they agree.’ You now remember what it meant—so the temptation is to rewrite it properly. Resist it. Rewriting replaces evidence with interpretation, and your current memory of what you meant is less reliable than it feels.
Why editing history is riskier than it looks
The original wording is data. It records what you actually knew and felt at the time—including the uncertainty. When you overwrite it, today’s confident reconstruction silently replaces yesterday’s honest ambiguity, and you can no longer tell which is which. If the reconstruction is wrong, the error is now permanent and invisible.
Append, with a date
The fix is a correction layered on top: ‘Clarified later: Option 2 meant the shorter contract; “they” means the landlord.’ The original stays; the clarification is visibly separate and visibly later.
- The original remains the source; the addition is interpretation.
- The date on the clarification preserves the true sequence of your understanding.
- Both layers are indexed, so search finds the note by either wording.
What deserves a genuine edit
Typos, autocorrect damage, and transcription errors are not history—they are noise, and fixing them in place is fine. The line is meaning: correct the record’s form freely, but never alter what it claimed.
Clarify on encounter
You do not need a cleanup project. Repair notes when you naturally run into them—in a search result, a review, or a clarification prompt. Every repaired note makes that corner of your history permanently more searchable, and the archive improves at exactly the rate you actually use it.
Four repairs that are always safe
The distinction between annotating and rewriting is easier to apply as a short list than as a principle:
- Naming a referent: ‘Clarified: “he” is Marek from the Vantaa team.’ The original pronoun stays.
- Resolving a relative date: ‘“Friday” was 14 March.’ Never overwrite the word ‘Friday’ itself.
- Recording the outcome: ‘This is what we did, and it worked.’ Outcomes belong beneath predictions, not inside them.
- Marking something superseded: ‘Reversed in June—see the later note.’ The wrong turn is part of the record.
The case against tidying, stated honestly
There is a real counter-argument: appended clarifications make notes longer and messier to read, and a note with three dated additions is objectively less elegant than a clean rewritten sentence. If your notes are drafts of documents, tidy them freely—that material is not evidence of anything.
The distinction is whether the note is a record or a working text. A record answers ‘what did I think then?’, and that question has exactly one correct answer, which editing destroys. A draft answers ‘what do I want to say?’, and only the current version matters.
Note also what appending does not achieve. It preserves honesty, not accuracy—your clarification is still a reconstruction, and if it is wrong, the note now contains a confident error alongside a truthful original. Dating it is what saves you: a reader, including you, can see that the interpretation came eight months later and weigh it accordingly.
Treat old notes like evidence: annotate, date, and preserve. Rewrite only form, never meaning—your past self deserves an accurate record more than an eloquent one.
