Jay articulates a philosophy he has come to live by: he is not searching for a favourite place, he is searching for favourite people — the ones who take him back to the heart of himself, who calm his nervous system and switch off the active mind. Riz responds by confessing he has carried a lazy narrative about disliking LA for years — a cliché about driving and sprawl and disconnection. But on the morning of this very interview, surrounded by his wife, child, and visiting family, the house full and alive, he woke up loving the city. It was the same feeling as being a child surrounded by clapping aunties. Home is the people. The place is immaterial. He was confronted with the realisation that the lazy narrative had been wrong all along.
The inner critic can drive you to extraordinary success. Then it can kill you. Riz Ahmed and Jay Shetty discuss how elite athletes toggle between the critic — who makes every point feel like everything — and the cheerleader, who can release that point immediately after it's over.
Our brains subjectively experience 50% of our entire lifetime between ages 0 and 8. That's why a single day felt enormous as a child and why years blur past now. The antidote, both Riz and Jay agree, is play — and protecting time for the Velcro-on-the-shoe moments.
Jay Shetty listened to Steve Jobs' Stanford commencement speech every single day for 9 months, calling it the best speech ever given because Jobs knew he was going to die.
Dan Gilbert's research found that the psychological immune system — the brain's ability to justify and find satisfaction in choices — activates most powerfully when a decision is perceived as irreversible.
Barry Schwartz's research found that maximizers — people who try to optimize every decision — tend to achieve objectively better outcomes but report lower happiness than satisficers who choose 'good enough.'
Research consistently shows that while people may initially regret poor decisions, in the long run they regret the decisions they didn't make — inaction — far more than the ones they took.
A study showed that men in committed relationships who briefly viewed 10 attractive women's faces reported a measurable decrease in relationship satisfaction immediately afterward, illustrating evolutionary mismatch with modern media.
Harvard psychologist Dan Gilbert, who previously didn't believe in marriage, immediately proposed to his long-term girlfriend after his own research showed that constraints increase satisfaction with choices.
Animals first sensed light 540 million years ago, triggering an evolutionary acceleration known as the Cambrian explosion within 10 million years.
It is estimated that half of all cortical activity in the human brain is involved in visual function, underscoring vision's central role in intelligence.
Cognitive neuroscience literature shows that by age 6, humans can recognize tens of thousands of different object categories — far more data than early AI systems were trained on.
Only about 3% of FDA-approved drugs have genuinely unclear mechanisms of action, making an unknown mechanism a meaningful early red flag for any compound.
