' But hours only count when they carry targeted experiential feedback — naive repetition produces experience without producing experiential knowledge.
Propositional knowledge — what you can read, hear, or memorize — is real and useful, but it cannot bridge the gap to performance.
Evolutionary radiation is defined simply as an increase in taxonomic diversity — and it directly causes elevated rates of speciation.
Evolutionary radiation — the rapid explosion of new species from a single lineage — is triggered by three mechanisms: specialisation into narrow parameters, colonisation of a new realised niche, and adaptation to new conditions.
The defining feature of the modern condition is a velocity mismatch: cultural and technological change now outruns biological evolution by orders of magnitude.
Evolutionary mismatch names the gap when previously adaptive alleles are no longer favored in a new environment.
Robert Greene argues that progress has not eliminated our ancient emotions or replaced our irrational wiring; it has merely shifted the surface forms they take.
Evolution's true currency is reproduction, not survival. A trait that actively damages your chances of living can still sweep through a population if it boosts mating success.
The word 'authenticity' gets misused as a synonym for expressing feelings or being true to a brand.
Most people chase competition because proven demand feels safe — there are success cases, established metrics, clear customers. But proven demand and saturated supply are two sides of the same coin.
Naval's framework flips the usual logic: competition is not a signal of a good market — it's a signal that you're copying what others are already doing. Copying adds supply to an existing pool, which drives prices toward commodity returns.
Shackleton's reputation isn't built on discovery or speed - it's built on what he could do when everything had already gone wrong.
Although the erector spinae is named for its role in extending the spine, it is also responsible for flexion and lateral flexion.
The erector spinae attaches from the sacrum all the way up to cervical vertebra C2, making it one of the longest continuous muscle groups in the human body.
Enzymes are specialized proteins that function as biological catalysts, accelerating chemical reactions without being consumed in the process.
The existence of the enteric nervous system shows that evolution repeatedly favors semi-autonomous modules that can handle local decisions without round-tripping to a central controller.
The enteric nervous system is a vast network of neurons embedded in the lining of the gastrointestinal tract that controls digestion largely on its own.
People who achieve the most durable success in competitive domains are almost always those who 'would do it for free' — and this isn't sacrifice, it's the mechanism by which results compound.
Munger's reframe treats outcomes as discrete events while the process is the continuous reality of daily life.
Most people treat work as a toll bridge to outcomes on the other side.
Human Chorionic Gonadotropin is secreted by the placenta right after implantation. Its only job is to keep the corpus luteum alive so it keeps producing progesterone — which prevents the uterine lining from shedding.
Robert Greene frames the desire to feel appreciated and understood as the deepest principle of human nature — more fundamental than status, security, or even pleasure.
A common failure mode when trying to understand others is projecting your own values onto their situation and then wondering why they react differently than expected.
Most people think empathy means asking how someone feels and listening sympathetically.
Most people assume slow responses to others' problems reveal laziness or indifference. The reality is more interesting: it's a built-in calibration bias — your nervous system treats your own crisis as urgent and others' as advisory.
When your own hand is on a hot stove, you yank it instantly. When someone else's hand is on the same stove, you hesitate.
Greene treats emotions as an ancient alarm system — physical arousal that hijacks attention toward something in the environment. The feeling is the signal itself, not a separate reaction to it.
Embryonic skeletal development proceeds through two distinct ossification processes.
The card links Effectiveness to Competitiveness, Efficiency, Evaluation with Criteria, and Stakeholder Satisfaction — signaling that no single number captures effectiveness.
This card defines effectiveness as the degree to which a business achieved its goals and solved its targeted problems — a measurement of results, not activity.
