14 Famous People Who Kept Journals (And What They Wrote)

Famous people who journal rarely use the page in the same way. Some keep diaries. Others fill notebooks, commonplace books, sketchbooks, work logs, or private pages where they can think without an audience. A journal, in this broader sense, is a place to observe, test ideas, rehearse beliefs, track progress, and remember what the mind would otherwise lose. I’ve spent years reading the journals of successful people and historically significant writers, artists, scientists, and leaders. What interests me is not

Mood Tracker Template: What to Rate Instead of 1-10

A mood tracker works when each day’s entry records four things: how much your mood interfered with what you had to do, how many hours you slept, one line on what happened, and one word for how irritable you were. The rating is the smallest part. The three fields beside it are what turn a column of numbers into something you can read. Almost every mood tracker template online asks you to shade a box from one to ten, or

Weekly Review Template: David Allen’s Own Checklist

A weekly review is a clearing pass, not a reflection session. Once a week you empty everything that has accumulated, look at what is actually in front of you for the next fortnight, and then let yourself think about what you might do next. It is closer to tidying a workshop than to writing in a diary. The original checklist is published free by the David Allen Company. It is eleven items, it fits on one page, and one of

Project Journal Template: The Ten Fields the NIH Uses

Six months into anything – a renovation, a thesis, a side business, a long repair – you can usually remember what you did. What you cannot remember is why you chose it over the other option, what the result actually was, and what you had decided to do next before the project went quiet. There is a published specification for exactly this problem. The National Institutes of Health issued Guidelines for Scientific Record Keeping in the Intramural Research Program at

Goal Journal Template: The If-Then Line That Works

A goal journal entry needs two things, and neither of them is a vision board. Write one goal specific enough that you could not fake having reached it, and hard enough that you are not sure you will. Then, underneath it, write the sentence that begins with “if” – the plan for the exact moment you would otherwise stop. That second line is the part with evidence behind it. The two statistics that hold up most goal-setting writing do not

Isaac Newton’s Notebooks: 49 Sins and a List of Questions

Isaac Newton kept two notebooks as a student, and neither of them is about physics. One is a pocket-book he bought blank for eightpence, whose first three pages are a coded list of every sin he could remember committing. The other is a list of things he did not know, written under headings he invented himself. Both survive. Both have been transcribed in full and put online for free. And between them they show a nineteen-year-old using a notebook for

Why Famous People Drew in Their Journals: 5 Examples That Will Change How You Take Notes

Most of us assume a journal is a place for sentences. But go and look at the notebooks of people who actually changed how the world thinks, and the pages are full of pictures. Not paintings. Not finished art. Quick boxes, arrows, stick figures, charts, half-finished diagrams. Drawing was not a separate hobby. It was how they thought. Across the journals of successful people I keep returning to, the same pattern shows up. The figures we now treat as singular

Xuanzang’s Lost Travel Records and the Book Made From Them

I went looking for the field notebooks of a seventh-century monk and found a library catalogue entry that quietly says somebody else wrote the book. Here is Stanford’s statement of responsibility for The Great Tang Dynasty Record of the Western Regions, the famous account of Xuanzang’s journey through Central Asia and India: translated by the Tripitaka-Master Xuanzang under Imperial Order ; composed by Śramaṇa Bianji Composed by Bianji. Not by Xuanzang. And here is the publisher of the English translation

Gauss Kept a Diary of Discoveries and Showed Nobody

The first entry is dated 30 March 1796. Carl Friedrich Gauss was nineteen. In Latin, it reads: Principia quibus innititur sectio circuli, ac divisibilitatis eiusdem geometrica in septemdecim partes Roughly, and this is a plain gloss rather than a scholarly translation: the principles on which the division of the circle rests, and its geometrical divisibility into seventeen parts. What he had done was prove that a regular seventeen-sided polygon can be constructed with nothing but a compass and a straightedge

The Dymaxion Chronofile: 1,201 Feet of One Man’s Life

There is an entry in Stanford’s archival catalogue that reads: Dymaxion Chronofile, Vol. 252 [5 of 6], 1964 Jan It covers 2 to 14 January 1964. Thirteen days. It is the fifth of six parts of a single volume, and that volume is the two hundred and fifty-second. It sits in Box 126, Folder 1, and it holds correspondence with Adlai Stevenson, a copy of the January 1964 NCAR Quarterly, and material relating to the TIME magazine cover story that

Derek Sivers Asks Himself Questions, Then Argues Back

Every journal prompt on this site was written by somebody else. That is the normal arrangement: a stranger supplies the question, you supply the answer, and the question is the part you are not expected to produce. Derek Sivers has kept a daily diary for over twenty years, and his entire method is the opposite. He writes his own question, answers it, and then sets about attacking the answer. The Only Living Subject in This Series Almost everyone profiled on
