The story of skill and talent is the story of myelin.
And the revolution is built on 3 simple facts:
1. Every human movement, thought or feeling is a precisely time electric signal traveling through a chain of neurons — a circuit of nerve fibers.
2. Myelin is the insulation that raps these nerve fibers and increases signal strength, speed, and accuracy.
3. The more we fire a particular circuit, the more myelin optimizes that circuit, and the stronger, faster, and more fluent our moments and thoughts become.
In basic terms: deep practice is built on a paradox that struggling in certain targeted ways — operating at the edges of your ability, where you make mistakes — makes you smart.
– Samuel Beckett
