What goes wrong when you ignore that context-independent behaviors?

The most common reason fails: Treating context-independent versions as inferior substitutes rather than as the essential core. The failure is building your entire system around the full-featured, context-dependent versions and treating the stripped-down versions as emergency fallbacks you never practice. When disruption hits, you have no muscle memory for the context-independent version, so it feels awkward and unfamiliar, and you skip it. The context-independent core must be practiced regularly — not just during emergencies — or it will not be available when you need it most.

The fix: List every habit you currently maintain. For each one, score it on five dependency dimensions: equipment (does it require specific objects?), location (does it require a specific place?), time (does it require a specific window?), people (does it require others?), and technology (does it require a device or internet?). Score each dimension 0 (no dependency) or 1 (dependency exists). Sum the scores. Any habit scoring 0 is fully context-independent. Any habit scoring 1 has a single vulnerability. Anything scoring 3 or higher is structurally fragile. Now select your three most important habits and, for each one, design a version that scores 0 — a version that requires only your body and mind. Write these three context-independent versions down. They are the seed of your behavioral survival kit.

The underlying principle is straightforward: Some habits should work regardless of where you are or what is happening.
