You have already explained everything to an AI. Three times over.
The goal, the sources, what was decided last week and why. Every conversation starts from nothing, and the earlier work is lost.
This book is the story of how I stopped. One space per subject, where the AI knows where an idea came from, recalls a trade-off, brings back an objection I had raised myself three weeks earlier. The deliverable goes to the client; the reasoning stays with me.
And nothing is lost. Every session leaves behind material that is connected and sourced. Six months later, a new subject starts with what the earlier ones learned. That is no longer a history — it is capital.
