How do I practice prerequisite relationships?

The most direct way to practice prerequisite relationships is through a focused exercise: Choose a skill you are currently trying to learn or recently struggled with. Write it at the top of a page. Now work backward: what must you be able to do in order to perform this skill? For each sub-skill, ask the same question — what must come before this? Keep going until you reach things you can already do confidently. You should end up with a tree or chain of 5-15 items. Draw arrows from each prerequisite to what it enables. Circle any prerequisite you have been skipping or assuming you possess but have never explicitly verified. That circled item is your actual starting point — not the skill at the top.

Common pitfall: Skipping prerequisites because they feel too basic. You will recognize this pattern when you repeatedly fail at something 'simple,' when explanations that should make sense remain opaque, or when you can follow a procedure but cannot adapt it to new situations. The deeper failure is confusing familiarity with mastery — you have seen the prerequisite material before, so you assume you possess it. But exposure is not acquisition, and recognition is not capability. Every time you skip a prerequisite, you are not saving time. You are borrowing against a debt that compounds with interest at every subsequent stage.

This practice connects to Phase 13 (Relationship Mapping) — building it as a repeatable habit compounds over time.
