Your Brain Physically Changes Every Time You Learn Something New. And It Works the Opposite Way You Think.
Your brain does not fill up when you learn. It destroys things. Synaptic pruning cuts connections that go unused. Myelin wraps the ones that get used, increasing signal speed from 1 to 100 metres per second. The expert brain is not a fuller brain. It is a leaner, faster, more ruthlessly efficient one. And myelin does not care whether what you are practising is correct.
