What does it mean that full automation means zero willpower requirement?

A fully automated behavior runs without any conscious effort or decision.

Example: You leave your apartment and lock the door. Three blocks later, a spike of doubt: did you lock the door? You cannot remember doing it. You cannot recall the sensation of turning the key, the click of the bolt, the tug to confirm. And yet you locked it — you always lock it. The behavior is so fully automated that it leaves no trace in conscious memory. There is no moment of decision, no flicker of effort, no internal prompt reminding you to do it. The cue fires (stepping across the threshold), the routine executes (key, turn, tug), and your conscious mind never participates. That is full automation. Not "easy to do." Not "mostly habitual." Fully autonomous — a behavior that runs itself.

Try this: Select five behaviors you consider habitual — things you do regularly without much thought. For each one, answer five questions honestly: (1) Do I ever have to decide to do this, or does it just start? (2) Does it consume any willpower, even a trace? (3) If I skipped it, would I notice something felt wrong, or would I simply not do it? (4) Is it triggered by a context cue, or do I sometimes need a reminder? (5) Does the quality of my execution degrade when I am stressed, tired, or distracted? Score each behavior: one point for every question where the answer indicates full automation (starts without decision, zero willpower, feels wrong to skip, cue-triggered, consistent quality). A score of five out of five is full automation. Anything less reveals which specific dimension still requires conscious involvement.
