Draw a line down a piece of paper. On the left: everything you're worried about. On the right: everything you can actually control. You'll find almost nothing on the right — and that's the revelation. The only thing anyone can write on the influence side is themselves. That single insight is the route to genuine agency.

Prompted by Huberman's confession that he has been using this tool weekly since encountering it in Drown Proof, Stumpf explains the exercise with characteristic directness [1] — Andy Stumpf "Draw a line down a piece of paper. On the left: everything you're worried about. On the right: everything you can actually control. You'll …" 04:59 . Draw a line down a standard piece of paper. On the left: concern — all the things occupying your waking hours, from social media drama to geopolitical events to long-ago relationships. On the right: influence — what you can directly control. The left side fills up fast; the right side contains almost nothing. Almost. Stumpf notes that the only thing anyone can truthfully write on the influence side is themselves: their self-talk, their time management, their response to events. That realization — that you have no control over what happens to you but absolute control over how you respond — is the pivot point. Stumpf uses the exercise about once a month now, often on long flights, as a way to identify unhealthy attachments and mentally redirect. Huberman credits it with remapping his own tendencies and giving him a far greater sense of agency, noting it even made him punctual for the first time.
Drawing a line on paper separating things you can influence (only yourself) from things you merely worry about resets your sense of agency and reduces mental noise.
Anxiety is not fear. Fear has an object — a wolf, a threat. Anxiety is the vertigo of standing at the edge of infinite possibility and knowing that choosing any one thing closes off all the others. Kierkegaard argued that the depth of your anxiety is proportional to the depth of your potential.
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.
