A Guide to Changing One Thing

You fixed your sleep in March. You also started magnesium, moved training to mornings, cut coffee after noon, and bought a different pillow. Something in there worked. You have no idea which one, so you are running all four, forever, at full price.

That is an attribution failure wearing the costume of a discipline problem. It is also why nothing you have ever fixed transfers to the next thing you need to fix.

Anyone who has debugged anything knows the rule and applies it without thinking about it. Change one line, rerun, read the result. Change four lines and the program either works or it does not, and either way you have learned nothing except a superstition you will now carry into every future version of the file.

Three moves.

One variable, one window. A change you cannot isolate is a change you can neither keep nor drop on purpose.

To be concrete: two weeks per change, one change at a time. That is twenty six experiments a year, which is slower than it sounds and considerably faster than the ten months you just spent learning nothing.

Write the prediction before you start. Memory quietly rewrites itself to match whatever you are currently doing, so the only honest record is one that predates the result.

To be concrete: one sentence, dated, containing a number. “By week two I expect to wake before my alarm four mornings out of seven.” Then leave it alone until the window closes.

At the end of the window it stays or it goes. “Probably helping” is the phrase that builds the stack in the first place.

To be concrete: read your sentence, compare it to what happened, and remove anything you cannot defend with that number. Same day, completely, not tapered.

Expect roughly one change in four to survive its window. That rate looks terrible next to the nine things you are doing right now, and it is the first honest number you will have held.

Nobody calls this superstition, because every item in the stack has a study behind it somewhere. You did not adopt them from studies. You adopted them in a batch, during a bad month, and you have been paying rent on all four ever since to protect the one you cannot name.
