How do I practice commitment stacking?

The most direct way to practice commitment stacking is through a focused exercise: Map your five most reliable daily behaviors — the things you do every day without fail, without thinking, without any structural support. These are your anchors. Now identify one commitment you have been struggling to keep. Write a commitment stack in this format: 'After I [reliable anchor behavior], I will [new commitment scaled to two minutes or less].' Install it today. Run it for seven days. At the end of the week, assess: did the anchor hold the new behavior in place? If yes, expand the scope slightly. If no, the anchor was wrong or the new behavior was too large — diagnose which one and redesign.

Common pitfall: Stacking onto behaviors that are not actually reliable. You tell yourself you will review your commitments 'after lunch,' but lunch happens at a different time every day, sometimes at your desk, sometimes with colleagues, sometimes skipped entirely. That is not an anchor — it is a moving target. The stack fails not because the technique is wrong but because the foundation is unstable. Commitment stacking only works when the base behavior is genuinely automatic and context-stable. If you have to think about whether the anchor will happen today, it is not an anchor.

This practice connects to Phase 34 (Commitment Architecture) — building it as a repeatable habit compounds over time.
