Build a bank. Decide from it.

You should create a bank of quotes and ideas. Think quotes from a book, ideas you hear on social, advice from a friend. Feed it to an AI and ask it to make all decisions from this place. Think of it like a sifter that ensures everything is built from this place.

I call it the bank, because your brain is your bank and this is like a brain to make decisions from.

How to start one

  1. 1

    One place

    A spreadsheet or a notes file. One entry per line.

  2. 2

    Write down where it came from

    Each entry gets a source: the book, the post, the friend.

  3. 3

    Say when it should come back

    Each entry gets a short line on when you want to see it again. Mine have a type, tags, a source and that line.

  4. 4

    Feed it to the AI

    Give the AI the whole bank and tell it to make every decision from it. Add to it whenever you hear something worth keeping.

An old habit

People have kept banks like this for centuries. They were called commonplace books: a notebook where the owner gathers quotations, maxims and anything else worth keeping, grouped under headings. John Locke wrote a method for arranging them by subject, published in English in 1706. Francis Bacon and Thomas Jefferson kept their own.

The purpose was to remember, and to have a store of material to write and decide from. The bank is the same habit, with an AI doing the reading.

Why give it to an AI

An AI starts every chat knowing nothing about you. If you hand it your bank, its answers start from your rules instead of the average of the internet. Ask it to name the entry it used for each answer. If an entry is wrong for you, you see it right away and fix it.

This week, write ten entries. One line each, with the source. That is enough to run the first test.

My daily motivator, El Jefe, is built on mine.

Your brain is your bank. Start filling it.
