Definition
Myelin is the biological fabric of excellence — experience-dependent wrapping of axons that speeds and stabilises the circuits you repeat with intensity.
Origin
Myelin increases conduction velocity and timing precision on frequently used pathways. Human skill-learning studies link deliberate training blocks to measurable white-matter plasticity over weeks — not metaphor alone.
Mechanism
Circuits myelinate when behaviour repeats with enough intensity to register — the pairing behind Myelin effort. Anchoring stacks use the same biology: stimulus + emotional intensity + repetition makes state callable; scrolling and narrating change without bounded reps rarely supply the pair.
Oligodendrocyte generation accelerates when animals learn complex skills; blocking precursors can leave acquisition incomplete — repetition without intensity, or intensity without cadence, both fail the wrap.
Example
You narrate change for a month without one bounded anchor rep — motivation talks, myelination does not. One daily nine-minute stack with real intensity beats another heroic weekend plan. That is B3 miss — repetition plus intensity never showed up.
Applications
Design lead measures as daily bounded reps — one honest anchor fire beats a heroic weekend. Pair physical and cognitive skill reps on the same mechanism map.
