Every short video we publish gets a page here - the video, a written breakdown, and the deck to actually learn it.
an index speeds reads and is paid for on every insert and update; the wrong index costs more than none
structural constraints repeat while surface details differ; recognizing the pattern is the skill
four bonds in every geometry; carbon chains scaffold the molecules of life
fungi digest externally and share more DNA with animals; they are the planet's recyclers
the same arousal as excitement, labeled as fear; reframing the label changes the performance
the anchoring bias cuts both ways; silence hands the anchor to the other side
the planning fallacy and single-point estimates; reference-class forecasting beats imagination
anchoring in negotiation; the first number sets the range the whole talk moves within
the primacy of questions over answers; a team that talks owns the problem
chest compressions buy time by manually moving blood; brain death begins at minutes without flow
static stretching before effort weakens the muscle; dynamic movement warms the nervous system instead
progressive overload; muscle adapts only to tension it has not met, and growth happens in recovery
thermic effect of food and processing; 100 kcal of almonds is not 100 kcal of soda
habit loops migrate to the basal ganglia to free up working memory; the cue fires before you decide

the default mode network is the brain's idle state; attention training shrinks its takeover
tradeoffs are comparisons between incommensurable values; you are not choosing badly, you are choosing between losses
the amygdala reacts before the cortex reasons; labeling the feeling is the fastest off-ramp
reconsolidation rewrites stored memories at each retrieval; eyewitness confidence is not accuracy
a leaking bucket needs infinite new customers; retention compounds where acquisition does not
a business dies in the unit, not the plan; CAC vs LTV on one customer tells you if growth scales
profit is an accounting opinion, cash is a fact; timing of revenue and expenses tells the survival story
