Greg Brockman keeps a diary.
Not a metaphor.
A literal, decades-long, type-into-his-laptop journal that he started in college when he was deciding what to study.
He kept it through Stripe.
He kept it through founding OpenAI with Musk and Altman.
He kept it through the brawl for control of the company in 2017 - the fight that's now being relitigated in a San Francisco courtroom.
This week, his journal became Exhibit 161.
Hundreds of pages. Stream-of-consciousness.
The kind of writing where you watch a person try to figure out what they actually want, in real time, on the page.
Read in court. Broadcast to the world.
"Ok so what do I really want? I want to want to be an engineer. But I think now is a crazy shot to be the one in charge..."
"cannot say that we are committed to the non-profit. don't wanna say that we're committed."
"the true answer is that we want him out."
Musk's lawyers found it in discovery.
The judge cited it in her ruling clearing the trial to proceed.
Brockman, on the stand, was asked who he wrote it for.
"Myself," he said.
That answer is the entire problem.
Journaling is one of the oldest good ideas
Marcus Aurelius wrote Meditations for himself.
We've been reading it for nineteen hundred years.
Buddhist monks treat reflective writing as a way to surface what you actually think — under the layers of what you're supposed to think.
Christian monks kept daily examinations of conscience.
Stoics did the morning and evening review.
Silicon Valley adopted the practice the way it adopts most things.
Late. Branded as a productivity hack. Dressed up in apps and templates.
But the underlying instinct was right.
Andy Grove kept a journal from the month Intel was founded in 1968.
The man who wrote Only the Paranoid Survive used a marble composition notebook as a survival tool.
It made him sharper than everyone else in the room.
Brockman is not the first founder to journal.
He's the first one whose journal became evidence.
The moment a private practice stops being private
There is no clean line between "personal reflection" and "discoverable record."
There is only the day a lawsuit is filed.
Before that day, your journal is your inner life.
After that day, it is a stack of pages with a Bates number.
Brockman wrote "we want him out" in November 2017 because that's what he was feeling.
Eight years later, that sentence is being read aloud by a man in a suit to a jury.
Whether the inference is fair is almost beside the point.
The sentence exists.
The sentence is in evidence.
The sentence is now part of how the world will remember the founding of the most consequential AI company in history.
The painful part is not that he was wrong to write it.
He probably needed to write it. Writing it was how he figured out what he actually thought.
The painful part is that the writing survived.
What this almost made me do
When I read the WSJ piece, my first instinct was: don't journal.
Then I sat with it for an hour and realized that's exactly the wrong lesson.
The same logic would tell you not to send emails.
Not to take notes.
Not to write anything down ever.
The Brockman story doesn't prove that journaling is dangerous.
It proves that typing candid thoughts about a specific named adversary into a synced cloud document during a contested business relationship is dangerous.
Those are not the same thing.
So I'm doing the opposite of what my instinct said.
I'm starting a journal this week.
Inspired by Brockman, not deterred by him.
The alternative - keeping everything in my head - is worse for the thinking, worse for the work, worse for the life.
But I'm doing it differently than he did.
The split that matters
Personal and business stay separate.
They don't share a notebook.
They don't share a tool.
They don't share a category of thought.

The personal journal is paper.
Cheap notebook. Kept at home. Written by hand.
Slow enough that the brain has to choose what's worth the effort of moving the pen.
Not synced anywhere.
Not backed up to a cloud.
Not subpoenable without a search warrant on my house.
The content is feelings. Training reflections. What I want.
What I'm afraid of. Gratitude. Abstract ideas.
The Marcus Aurelius bucket.
The business log is something else entirely.
Structured. Factual. Dated.
Written from the start as if it might be read by a stranger in a courtroom.
Decisions and the reasoning behind them. Meeting notes. Timelines.
The format that holds up in litigation because it was built to.
The harassment timeline I've been keeping for the past eight months is the model.
Contemporaneous. Sourced. No editorial about anyone's character or motives.
The two never mix.
Feelings about a counterparty go on paper, in initials, never named.
Strategy involving that counterparty either goes in the structured log in factual form — or doesn't get written down at all and lives in a verbal conversation with my COO or my lawyer.
I'll be tempted to break this rule.
Everyone is.
The whole reason a journal works is that it lets you say the thing you can't say anywhere else.
The discipline is to notice when "the thing I can't say anywhere else" is also "the thing that would hurt me if anyone else read it."
And to route that thought to a channel where the only audience is me, the page, and a pen.
The harder version of this lesson
Brockman's mistake wasn't journaling.
It was generating a permanent, searchable, recoverable written record of candid views about a named live counterparty.
Most of us are doing some version of this every day.
Slack DMs venting about a coworker.
Notes app drafts of emails we never sent.
Long ChatGPT conversations processing what we really think about a deal partner.
We treat these surfaces as private because the UI calls them private.
The UI is lying.
Anything typed into a third-party tool is, eventually, discoverable.
The Brockman story is the highest-profile version of a lesson that applies to all of us, all the time.
The right response is not to stop thinking on paper.
It's to be honest about which paper you're using.
Marcus Aurelius wrote on parchment.
Brockman wrote on a laptop.
Same instinct.
Different medium.
Very different consequences.
I'm starting today.
Cheap notebook. Five minutes.
The single prompt: what's actually on my mind right now.
Whatever I write, only I will read.
That's the point.
