Our perception of sensing then reacting is an illusion. The brain constantly predicts the next moment based on past experiences, preparing actions before sensory information fully arrives. This predictive process is far more efficient than constantly reacting to the world from scratch, meaning we act first, then sense.

The mind wanders 50% of the time not by accident, but as an evolutionary feature. This "spontaneous thought" acts like a replay function, repeatedly firing neural patterns from recent experiences to strengthen their connections and embed them as long-term memories.

Scientific literature suggests humans have between 22 and 33+ physiological senses, including balance, proprioception, and awareness of internal states like bladder fullness. This reframes human potential, suggesting we are capable of perceiving far more than we commonly acknowledge.

In humans, learning a new skill is a highly conscious process that becomes unconscious once mastered. This suggests a link between learning and consciousness. The error signals and reward functions in machine learning could be computational analogues to the valenced experiences (pain/pleasure) that drive biological learning.

While on a career break, the author's deepest anxieties about failure and irrelevance were perfectly articulated by his young son. This reveals a dynamic where children can absorb and voice their parents' unspoken fears, serving as an unwitting mirror to the subconscious.

The idea that language creates thought is backwards. Pre-linguistic infants already have a sophisticated understanding of the world (e.g., cause and effect). They learn language by shrewdly guessing a speaker's intent and mapping the sounds they hear onto thoughts they already possess.

Children's brains are constantly processing overwhelming new data. From a neuroscience perspective, re-watching the same movie or song is a calming behavior that reduces anxiety by presenting familiar, predictable information, providing a respite from the neurological load of constant learning.

Having young children is like having a "joy jukebox" because they experience everything for the first time. This gives parents a chance to indulge in and appreciate simple wonders again, from a fresh perspective. This re-framing highlights a key, often overlooked, benefit of parenthood for ambitious individuals.

The right hemisphere of the brain doesn't define a separate "you." It experiences the world as a unified whole, integrating all sensory input into one big picture. This is the neurological basis for "flow states" or feelings of transcendence, where the boundary between self and the world dissolves.
