Andrew Roberts keeps his diary as a selective morning record rather than a compulsory nightly log. He writes pretty much the next morning, before beginning his book work, because waiting weeks would allow details to fade and writing after drinking is unreliable. He does not force an entry when nothing interesting happened. When there is something to preserve, he chooses the most interesting part of the day, records notable things people said or did, and limits the entry to about 500 words. The mechanism balances freshness, selectivity, and brevity: morning timing improves recall, selective capture raises the signal, and a short ceiling keeps the practice sustainable. The result is a personal archive without the burden of documenting every ordinary moment.
Origin
Roberts describes the diary practice he has maintained across more than forty years. Extracted from The Tim Ferriss Show.
Core principles
- 01Write while the previous day is still fresh
- 02Skip days with nothing worth recording
- 03Select significance instead of logging everything
- 04Keep the entry short enough to sustain
How to run it
- 1
Return the next morning
Review the previous day while its conversations and events remain fresh.
Pro tip Place the diary before the day's main writing work.
Watch out Leaving the entry for two weeks risks losing the details that made the event worth preserving.
- 2
Apply the interest test
Ask whether anything interesting happened; make no entry if the answer is no.
Pro tip Let silence preserve the diary's signal-to-noise ratio.
Watch out A forced daily quota can fill the record with events that do not matter.
- 3
Choose one focal point
Select the most interesting part of the day rather than attempting a complete chronology.
Pro tip Prioritize a moment that reveals character, meaning, or change.
- 4
Capture words and actions
Record the interesting things people said or did while they can still be recalled.
Pro tip Preserve concrete details instead of replacing them with a generic verdict.
Watch out Do not rely on handwriting or notes that you will be unable to understand later.
- 5
Stop at the ceiling
Keep the finished entry to no more than roughly 500 words.
Pro tip Use the word limit to force selection, not to compress every event into the entry.
In the wild
Roberts writes first thing in the morning before his book writing. If the day contained something interesting, he selects its most interesting part and records notable words or actions in no more than about 500 words.
→ He creates a long-running record that he describes as relaxing and calming.
Common mistakes
Waiting too long
A delay of weeks weakens recall and makes specific dialogue or action harder to preserve.
Forcing empty entries
Writing when nothing interesting happened adds volume without adding a meaningful record.
Recording the entire day
The method depends on selecting the most interesting part, not reproducing every event.
Is it for you?
Best for
It is best for people who want a durable personal record and can reflect briefly in the morning.
Not ideal for
It is not ideal for people who need a complete contemporaneous log of every event.
