What does it mean that context-independent behaviors?

Some habits should work regardless of where you are or what is happening.

Example: Anika has meditated every day for five years. During that time she has moved twice, traveled to eleven countries, survived a hospitalization, lost a parent, changed jobs, and gone through a divorce. Her meditation practice survived all of it — not because she is extraordinarily disciplined, but because her practice requires nothing. No cushion, no app, no quiet room, no specific time, no specific posture. She counts ten breaths. She can do it in a departure lounge, in a hospital bed, in the back of a taxi, at a funeral. The practice has zero context dependencies, which means there is no disruption capable of removing the conditions it needs, because it needs no conditions. It is the single most resilient behavior in her system, and it anchors everything else.

Try this: 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.
