Not your life story. The thing you actually know — how you read a room, why you never do it the way the textbook says, the three mistakes everyone makes in their first year. It exists in your hands and nowhere else, and it leaves when you do.

Why it never gets written
Ask an expert to write down what they know and they freeze, because the interesting parts do not feel interesting from the inside. The judgement you make in half a second took thirty years to build, and it does not announce itself as knowledge. It just feels obvious.
It is not obvious. It is the whole book. But it only comes out when someone who does not know the work asks why you did that, and then asks again.
That is the job. Oshin asks the second question.
The line that matters
Nothing is invented. Every claim in the book traces back to a recording of you making it, and you can hear the moment you said it. Bring in the people you trained, the partner who disagrees with you, the client from 1998 — their accounts sit alongside yours, attributed.
What this costs
The thing you have meant to do since you turned sixty.
—Two days of talking. Your judgement, in your words, with the recordings underneath.
$2,500Someone else writes it, and you spend months correcting them.
$25,000+Forty-five minutes. We work out what the book is, who reads it, and whether there are two days in it. If there are not, you have lost forty-five minutes and gained a table of contents.
