"Use tiny prototypes to outsmart fear of change A neuroscience paper cited in the conversation shows that the brain finds it less threatening to endure familiar pain than to take action to solve it — the amygdala fires harder for novelty than for suffering. The speakers' solution is to make the action so small it barely registers as change: "take really small steps called prototypes — try something, have a conversation with somebody, see what it"s like.' Even the iPhone required over 300 prototypes before the team knew what they were building; applying the same process to life decisions means you always learn something useful, regardless of outcome.
