Nick Epley noticed he was walking through his office building every morning with his head down, passing dozens of people without a word. He started a 'hello walk' — keeping his head up, smiling, greeting everyone by name. It changed his mood before he even reached his desk. Small habits, repeated daily, reshape who you are.

Huberman frames the final section around modeling: just as young animals learn social behavior from elders, children absorb social norms from watching adults in unremarkable moments. Epley is honest about his own imperfections — a quick temper that can flare in frustration — and describes the deliberate practice of removing himself from situations before responding rather than reacting. His most concrete tool is the 'hello walk': where he used to walk the 150-yard atrium of his building head-down, now he keeps his head up and greets every person by name — custodial staff, administrative assistants, faculty. It brightens his day before he reaches his desk, and it has become automatic. The chapter closes with a mutual exchange about classroom rules as a social media moderation strategy: Huberman applies the same norms online that he would in a classroom, and reports that regular commenters feel safe enough to engage there precisely because those norms hold.
AI nailed Andrew Huberman's vertigo-vs-low-blood-pressure diagnosis because that pattern has been reported millions of times. But every patient's liver is different and data on liver surgeries is scarce worldwide — making solo robot surgery dangerous. The rule is simple: data abundance means AI can help; data scarcity means keep the human in the loop.
Fei-Fei Li's father had liver surgery performed by a da Vinci robot guided by a surgeon. The result: 10 times less blood loss than a typical procedure. This isn't replacement — it's the gold standard of human-machine collaboration, where the human's judgment and the robot's precision combine.
US drug overdose deaths fell from 110,000 to roughly 70,000 — the biggest CDC-recorded single-year drop ever. Men's rates fell 27% in one year, and the steepest decline of all was among 15–24-year-olds, down 37%. The crisis narrative around young men needs to make room for signs of genuine progress.
Kessler thought his grief expertise would protect him. It didn't. When his son David died unexpectedly, he found himself on the floor — and eventually realized that acceptance alone wasn't enough. That unmet need became the sixth stage: finding meaning.
Grief isn't just death — it's any unwanted change. Kessler lectured at Coca-Cola and General Mills not because they had lots of funerals, but because change management is grief management. People who grieve well live well.
Witnessing someone's grief isn't just emotional support — it's an essential act of healing. Kessler argues grief is a severance and connection heals it. But real witnessing has two steps: seeing the pain AND affirming the person's capacity to recover.
Avoiding grief isn't free — it's exhausting. Kessler's beach ball metaphor nails it: pushing a small balloon down is easy, but holding a massive beach ball underwater takes constant, draining energy. Unattended feelings don't disappear; they just consume you.
Most people try to control their environment to avoid triggers. Kessler flips this entirely: triggers aren't problems to manage around — they're a detailed map to your pain and your healing. Every trigger points directly to what needs attention.
Running from pain doesn't leave it behind — it accelerates the chase. Whatever we run from pursues us, and whatever we face transforms us. Both Kessler and Lewis Howes testify to knowing both roads firsthand.
