What does it mean that habit stacking formula?

After current habit I will new habit — this is the fundamental stacking formula.

Example: A physical therapist wanted to build seven new micro-habits into her morning but had failed at every one individually. She stopped trying to install them separately. Instead, she pulled her habit scorecard from L-1038, identified her five most reliable morning habits, and wrote a stacking formula for each link: "After I pour my coffee, I will take three deep breaths. After I take three deep breaths, I will open my journal and write one sentence. After I write one sentence, I will read one page of my current book." She added one link per week, never two at once. By week five, the entire sequence ran automatically — each completed behavior firing the next like dominoes, producing a thirty-minute morning routine that required no willpower, no alarms, and no decisions.

Try this: Pull your habit scorecard from L-1038. Circle your five most reliable positive habits — behaviors you perform every single day without exception, with clear physical endpoints. For each one, ask: Is there a new behavior I want to install that fits this context (location, energy level, available time)? For your best anchor-behavior match, write the full stacking formula: "After I [specific endpoint of current habit], I will [new habit described in concrete physical terms, under two minutes]." Post the formula where the anchor habit occurs. Run it for fourteen days, tracking daily execution (fired/missed) and noting any days the anchor itself did not occur. After fourteen days, evaluate: if the new link fired on twelve or more days, it is encoding. Add a second link. If it fired on fewer than twelve, diagnose whether the problem is the anchor (unreliable), the new behavior (too large), or the context (incompatible).
