Main idea

Two sentences resemble each other enough to be filed together, and yet they don't have the same lifespan. "Write LinkedIn posts based on the three articles published in issue no. 16 of the magazine" won't move before the work is done. "Today, we're breaking article 2's ideas out into distinct posts" will have changed before the afternoon is over. Both answer the question "what are we working on?", and it is that homonymy that gets them written in the same place.

The goal and the attention are therefore held separately: the goal in the folder for stable things, with the perimeter and the working rules; the attention in the folder for the living state, with the current plan and the actions under way. The first file isn't rewritten once in the whole life of the mission, the second is rewritten at every session.

Confusion costs in both directions, and both are observable. An assistant given the day's focus as its goal redefines the mission around a detail: breaking up article 2 becomes the objective, and the other two articles disappear. An assistant given only the goal works with no depth of field: "write LinkedIn posts" doesn't say which sub-problem has to be precise right now. The goal gives the direction, the attention gives the focal length — and you redo the focal length ten times without ever touching the direction, just as a job doesn't change because you spend the afternoon on one task.

Why it matters

This gives a filing criterion that isn't thematic. Two files about the same subject don't have to sit side by side if they don't go stale at the same rate: what decides their place is how often they get rewritten, because that is what decides what you can reload without rereading.

It also makes drift detectable. When the goal file has been modified, you know something happened — whereas drift slipped into a file you rewrite every day leaves no visible trace.

Nuances and limits

The separation assumes a genuinely stable goal. On an exploration where the objective gets rephrased as you discover the terrain, the goal file moves as much as the attention file, and the distinction stops settling anything — it then becomes a dating discipline rather than a filing rule.

And a focus that never changes over six weeks doesn't prove the work is stable: more often than not it signals that the attention was never stated explicitly, and that the file stayed on its first line.

Open questions

• By what sign do you recognize that a focus carried over session after session has in fact become a rephrasing of the goal — and that the line has to move up into the stable file?
