Acts
Durable knowledge
Decisions worth keeping live in a document you own, not a scrollback you will never find again.
Chat answers are use-once by default: brilliant at the moment of need, unfindable by the time the need recurs. The ninth law for daily life says convert at the moment of value. When an answer is one you will act on later, need again, or hand to someone else, make the machine produce the durable form on the spot: the playbook, the checklist, the table, saved somewhere you own.
The conversion is cheap precisely once, while the context is loaded. Recreating the same answer next month costs the whole conversation again, if you remember to have it. A personal knowledge base built from these distillations compounds; a chat history does not, no matter how good the chats were.
How to practice it
Convert at the moment of value.
The answer you'll need again becomes an artifact now, while the context is warm. Later costs the whole conversation again.
Ask for the durable form.
A playbook with links, a checklist, a table: name the format you'll actually use when you return.
Save where you own.
Notes app, files, docs: your store, your search. The chat scrollback is a lease, not a library.
Date and title for future you.
The artifact will be found by someone who forgot this week existed. Write its label for them.
