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.
Predictions that AI would eliminate radiologists were spectacularly wrong. Since those predictions, Mayo Clinic's radiology staff grew 55% and the specialty became the second-highest paid in medicine. The reason: AI automated scan-reading, but only 36% of a radiologist's time was ever spent doing that.
Self-help fails because people are sold one universal cure by the hyper-responders who had a transformative result from it. The real problem is context: every method works for the right person at the right time, which is almost never you just because the author says so.
Spencer Greenberg was once so socially anxious his heart pounded just approaching a stranger. His therapist gave him homework: go to a bar alone, talk to 5 strangers. Starting with asking for the time, he worked up to asking men for hugs — and his anxiety fell dramatically in 6 months.
A person who flies regularly but obsessively checks weather forecasts before every flight is not doing exposure therapy — they're teaching their brain that flying is only safe with the ritual. Safety behaviors prevent the brain from ever learning that the feared thing is actually fine.
The worry-time technique assigns all worries to one scheduled slot (e.g. 5 PM). Every time a worry surfaces, you write it down and ban yourself from engaging with it until that time. When 5 PM arrives, most worries feel trivial and the act of batch-worrying exposes how little it actually accomplishes.
In a randomized study of 20 habit techniques, 'habit reflection' stood out: recall a past habit you successfully built, write down what helped you succeed, then apply those same strategies to your new habit. It works because it's self-adapting — it uses whatever worked for YOU.
The tiny habits technique — always having a minimal version of your habit you can do when life gets in the way — keeps the mental machinery of habit formation from breaking. Paradoxically, people given a tiny-habit fallback option were MORE successful at the full habit, not less.
Fears and worries act like playground bullies — they want to ambush you. But when you deliberately seek them out and choose the time of engagement, they lose their power. The volitional act of starting the fight on your own terms is one of CBT's most underappreciated insights.
Most downtime defaults are things you regret immediately after — phone scrolling, binge TV. 'Glad you did it' activities meet the same need for rest but leave you feeling like you spent your time well. The switch from a bad screen to a documentary, a book, or a walk costs almost no extra effort but compounds into identity over time.
