Entries with direct documentation, named routines, or first-person reporting.
Evidence is not uniform. High means direct documentation or a named routine. Exploratory means the signal is interesting but thinner and should not be treated like gospel.

Athlete / Gymnastics
Signal
Writes down worries, then confines them to one set hour a day
Why it matters

Athlete / Swimming
Signal
Daily journaling to break emotional suppression

Athlete / Sprinting
Signal

Uses the journal as a pre-performance commitment device, not just a postmortem.

Why it matters
Turns vague self-improvement into a written, checkable list instead of a feeling.
Says he writes down, every year, where he is not great, then works out concretely how to fix it. This is a yearly written review, not a daily journaling habit.
Athlete / Tennis
Signal
Ends most days writing by hand about his activities and how they affected him emotionally
“I try to write on a paper with a pen. There's something about that ritual where you're emotionally cleansing... spending some quality time with yourself and your thoughts.”
Why it matters
Specifies handwriting, not a notes app, as part of what he calls an emotionally cleansing ritual.
Described the habit on 60 Minutes (CBS) in 2023, and separately discussed journaling as part of his mental toolkit, alongside meditation and breathing work, in a 2020 interview.
Athlete / Tennis
Signal
Writes herself focus messages and rereads them from under her towel during changeovers
“They are messages that I write myself, just keeping focused on the match... I've been looking at notes for decades.”
Why it matters
A physical note she can reread mid-match works as a commitment device when concentration is already under strain.
Explained the practice to reporters at Wimbledon 2019, after cameras caught her reading scraps of paper from under her towel between games during a three-set win over Alison Riske.
Founder / OpenAI
Signal
Fills a pocket spiral notebook every 2-3 weeks, then tears out and discards the pages once he has worked through them
“I think of writing as externalized thinking. I still, if I have a very hard problem... have not found anything better to do than to sit down and make myself write it out.”
Why it matters
The notes are disposable on purpose. The value is in writing them, not in keeping an archive.
Described the habit, down to his specific pen and notebook, on the How I Write podcast; Fortune reported it in 2025 alongside similar habits from Bill Gates and Richard Branson.
Founder / Virgin Group
Signal
Carries a notebook everywhere and goes through dozens of them a year; credits several Virgin businesses to ideas caught this way

Why it matters
Treats the notebook as a capture device for other people's ideas as much as his own.
Wrote this on his own Virgin blog; Fortune re-quoted it in 2025 alongside Sam Altman's and Bill Gates's note-taking habits.
Founder / Spanx
Signal
Carried the same style of notebook for over 20 years to write down ideas the instant they arrive
“Before Iphones, I carried the same type of notebook for years. I'm always writing down ideas, thoughts and solutions to problems... The second you write something down is the moment you give thoughts in your head actual life.”
Why it matters
Treats the act of writing itself, not just the note, as what turns a stray thought into something real.
Posted this on her own LinkedIn in 2021, describing pulling off the road to write an idea down before it could disappear.
Founder / Bridgewater Associates
Signal
Nearly 30 years of writing down the principles he was forming as he formed them
“About 30 years ago I got in the habit of writing down what I was going after and how I went after it (i.e. my principles) so I've done that ever since.”
Why it matters

Wrote this on his own Substack in 2026, describing the habit as one of the two practices, along with meditation, that most changed his life.
Musician / Pop

Notebook pages visible in documentary footage
Why it matters
Turns raw, messy, and sometimes ugly thought into usable creative material.

Musician / K-pop
Signal
@rkive as a digital commonplace book
Why it matters

Screen / Actor and musician
Signal
Journals as one part of a nightly wind-down routine
Why it matters
A small, concrete habit inside a broader mental-health routine, not a cure-all.
Has shown journaling as one step in her evening self-care routine, alongside a walk, a heating pad, and turning off screens before bed.
Screen / Film
Signal
Recorded a public "My Audio Diary" entry in January 2021
Why it matters
A spoken, shared reflection is a different act than a private written page: no draft to hide behind.
Posted a recorded audio diary reflecting on a hard year and naming what she was grateful for. Her separate, well-documented depression recovery is credited to therapy and medication, not journaling.
Screen / Actor and activist
Signal
Writes three joyful things, three acts of kindness, three things done well, daily
Why it matters
Adds structure to a schedule that is otherwise chaotic and externally driven.
Described a daily journaling ritual on British Vogue's "In the Bag" in 2023, and has separately said she keeps close to ten different journals for different subjects: dreams, yoga, acting, conversations.
Creator / Podcasting and fashion
Signal
Podcast as a public reflective notebook
Why it matters
Uses voice because it is faster, lower-friction, and easier to review than stacks of handwritten pages.
Keeps a physical journal but increasingly treats her podcast as a recurring audio journal for processing questions and patterns in real time.

Diaries since age 13, 120 scanned diary pages released across four deluxe Lover editions (2019)
“I started writing in diaries when I was 13. These are the four deluxe editions of this album, and each one contains 30 pages of my diary entries from my life.”
Why it matters
Publishing dated, handwritten pages turns private teenage writing into primary-source evidence instead of a songwriting myth.
Read her own diary pages live on YouTube in August 2019 while unveiling four deluxe editions of Lover, each reprinting 30 pages of handwritten diary entries spanning ages 13 to 27. This entry was previously removed from this page after an earlier pass could not confirm it. It is readmitted here once both the Elle livestream transcript and the New York Times account of the same release were checked directly.
Actor / Film

36 years of handwritten diaries, since age 14, mined directly for his 2020 memoir Greenlights
“It was intimidating to go look at 36 years of my diaries... I'd been putting this off for 15 years and finally got some time and the courage to go, 'Let's go see what they are.'”
Why it matters
Treats the diary as raw material to be reread and edited, not just a place to vent.
Wrote Greenlights (2020) entirely from 36 years of his own diaries, going back to age 14. Told GQ he spent 52 days in what he called solitary confinement sorting through them, and that he learned early to keep writing in the diary when things were going well, not only when he was in crisis.
Entertainer/media / Television and publishing

Journaling every day since age 15, ending each entry with five things she is grateful for
“I've been journaling since I was 15; I still have my journals from when I was 15. I always end with the five things that I'm grateful for.”
Why it matters
A fixed daily format, five gratitudes, every entry, is easier to sustain for decades than open-ended reflection.
Told People magazine in 2023 that she still has her journals from age 15 and has kept the same five-gratitude format ever since. Not built as a standalone page on this site: her own site already owns the search results for her name plus journaling.
Musician / R&B and piano

Diaries since childhood, the source material for the concept album The Diary of Alicia Keys (2003) and the book More Myself (2020)
“I have a lot of diaries and I love paper, I'm a paper fanatic, I love books that have empty pages.”
Why it matters
Uses writing to understand a feeling before she can talk about it out loud, not after.
Told The Talks in 2016 that writing something down is how she processes what she cannot yet say. In the same interview she said she had stopped keeping a diary day to day and wanted to start a new one, so this is a lifelong habit with real gaps, not an unbroken streak.
Actor / Film and theater
Signal
Started a daily journal, on his therapist's recommendation, that begins every entry with the words "I feel"
“I, in the last year, started a journal that starts with two words: 'I feel.' It was a bit of homework... And now every morning I do it, obsessively, because I realized how stunted I was.”
Why it matters
Forces a specific emotion word instead of a vague one like "confused," which his therapist flagged as code for feeling more than one thing at once.
Described the practice to SELF magazine in 2022 as a way to unlearn a mental habit of suppressing emotion that started in his childhood in Australia.
Musician / K-pop
Signal
Has kept a diary since her 2008 debut, and still writes in it, though less often than before
“I still write in my diary, but I'm not as obsessive about it anymore.”
Why it matters
An honest update rather than a fixed origin story: the habit continued for over a decade but changed shape.
Told Vogue Korea in 2022 that she used to cling to every note-worthy thought but now lets most of them go, keeping only what still matters by the time she sits down to write.
Actor / Bollywood and Hollywood
Signal
Kept a handwritten diary during the press run for Quantico in 2015
“It's an old-school version... no laptops or iPads for this one. I simply pen my thoughts, emotions and experiences.”
Why it matters
A real, quoted practice, but a one-off tied to a single press cycle rather than a described ongoing habit.
Told The Hollywood Reporter she was keeping the diary during her Quantico press tour. Coverage of the published entries treated them as promotional material as much as personal reflection, which is why this entry is rated medium rather than high.
Historical / Track and field, 1936 Olympics
Signal
Kept a handwritten diary crossing the Atlantic to the 1936 Berlin Olympics
“Wrote a letter to my wife tell her about the trip. Took a light work out and then a nice bath... Kiss her picture often and wishes she was with me.”
Why it matters
A first-person, dated account of the days before his four gold medals, in his own hand, not a retrospective.
His travel diary, titled 'My Travels Abroad,' is held and transcribed by Ohio State University Libraries.
Historical / Boxing, 1969 exile
Signal
Kept handwritten "National Diary" notebooks in 1968 and 1969, recording day-to-day appointments and notes
Why it matters
A working document, not written for an audience, from the years he was barred from boxing for refusing induction.
A page from his 1969 diary, recording arrangements for a Randolph-Macon College speaking engagement and its $1,000 fee, has sold through Sotheby's with the diary's authenticity guaranteed.
Historical / Robben Island, 1976-1989
Signal
Recorded dreams, health, visits, and reading in desk-calendar diaries through 13 years of imprisonment
Why it matters
Survived intact despite two years of diaries, 1978 and 1985, still missing, and is now archived rather than paraphrased.
The Nelson Mandela Foundation holds the diaries in its archive: desk calendars he began ordering in 1976, which turned into daily notes on dreams, health, visits, and reading.
Historical / US Army, 1910-1945
Signal
Diaries spanning 1910 to 1945, fully digitized by the Library of Congress
Why it matters
Covers the Mexican Punitive Expedition and both World Wars, revealing his own private candor about command decisions.
The Library of Congress digitized the diaries as part of the wider Patton papers, describing them as revealing his candor about himself, personally and professionally, through the North Africa, Sicily, France, and Germany campaigns.
Not every named figure journals. These three said so themselves, on the record, and the receipts are worth keeping next to everyone above.
CEO, Tesla and SpaceX
“I never take notes.”
Posted on X (formerly Twitter) in March 2023, without elaborating.
Founder, AngelList
“I'm both lazy and really focused on being present, so I think taking notes is the same as taking photos when you're on a trip. All it's doing is taking you out of the moment.”
Explaining, on The Knowledge Project podcast, why he does not take notes on what he reads.
Musician
“I never write anything down.”
Told the BBC he wrote "Castle on the Hill" line by line into a microphone, with no notebook and nothing drafted on paper first.
