axial tilt changes the angle and hours of sunlight; distance from the sun is not the reason
glymphatic clearance and memory consolidation; the brain literally washes itself while you sleep

inside view vs outside view; using a reference class instead of imagining the smooth run
activation energy; consistency builds the identity that intensity cannot
cue routine reward; you redesign the cue and the environment, not the amount of effort
every yes is a no to something else; the real price is the best thing you gave up
vividness stands in for frequency; how easily an example comes to mind is not how often it happens
