Kiley

“Describing good relatedness to someone, no matter how precisely or how often, does not inscribe it into the neural networks that inspire love. Self-help books are like car repair manuals: you can read them all day, but doing so doesn't fix a thing. Working on a car means rolling up your sleeves and getting under the hood, and you have to be willing to get dirt on your hands and grease beneath your fingernails. Overhauling emotional knowledge is no spectator sport; it demands the messy experience of yanking and tinkering that comes from a limbic bond. If someone's relationship today bear a troubled imprint, they do so because an influential relationship left its mark on a child's mind. When a limbic connection has established a neural pattern, it takes a limbic connection to revise it.”
― Thomas Lewis, A General Theory of Love
