​Creatine: One of the most well-researched and effective supplements for enhancing muscle strength, cognitive function, and overall energy production, with benefits extending beyond athletes to general health and aging.

It supports brain health, muscle recovery, and even metabolism, making it a simple, safe, and cost-effective addition to nearly anyone’s daily routine.

I take creatine daily. NEVER trust supplements from SCAMazon. Full of fakes with who knows what inside. Buy direct or don't bother.

​NEW Premium Notes​

​A Rational Conversation on Where AI is Actually Going | Benedict Evans on Lenny’s Podcast​

  • If you're worried about AI or just confused about where things are heading, these Premium Podcast Notes will teach you a lot and make you feel a little less replaceable. Unlike the online doomers spouting off about how AI will destroy this or eliminate that, Benedict Evans provides historical perspective on technological cycles that puts some of the more aggressive AI predictions on ice — for now, at least.

​Improve Flexibility with Research-Supported Stretching Protocols | Huberman Lab Essentials​

  • Most people think stretching is just about pulling a muscle until it loosens up. It is not. It is a nervous system event, and once you understand that, everything about how you stretch changes. Huberman breaks down the actual neuroscience of why your body resists flexibility, what overrides it, and the exact protocol research says works best. Spoiler: you have been stretching too hard.

​Gustav Söderström, Spotify | David Senra​

  • AI allows companies to take control of the user or give back control to the user. In an industry like music, which is widely viewed as unequivocally good for society, it’s important not to pollute its integrity with cheap engagement tactics. Gustav Söderström, the recently appointed CEO of Spotify, explains how he’s upholding this responsibility by ensuring every minute on the app is “time well spent” and leaves users with “no regrets” — a standard most apps fall far short of today.

Top Premium Takeaways Of The Week


​A Rational Conversation on Where AI is Actually Going | Benedict Evans on Lenny’s Podcast​

  • Right now AI feels like the internet in 1997. Exciting, tools sort of work, but practical functions aren't fully clear
  • Is your job a job? Or is your job just a task? If it's just a task, it will likely be automated away
  • Predicting which industries AI will hit hardest is "the most ridiculous bunch of ??????? ??????????." The internet crushed taxis with Uber. It also enabled Airbnb with almost no effect on hotels
  • Since the 1800s, new technology has always cycled the old jobs out and the new jobs in. The old jobs are known. The new jobs are ???????. That asymmetry is why there's always more fear than excitement
  • Historical averages mislead during major transitions. If you are a 22-year-old in 2026, AI may have already ????? ???? ?????? ???​
  • "Don't stick your head in the sand. That gives you a great feeling of ????? ?????????. But that's not going to help. What helps is you ?????? ?? and completely submerging yourself in it"
  • Even if AI hits a brick wall tomorrow, it's still a useful and transformative technology. "It will all probably be okay"

​

​Improve Flexibility with Research-Supported Stretching Protocols | Huberman Lab Essentials​

  • Most people think stretching is just about pulling a muscle until it loosens up. It is not. It is a ??????? ?????? event
  • The key number: at least 5 minutes per week per muscle group for real lasting change
  • Static stretching before exercise can actually ?????? ??????????? in running and lifting, so save it for after
  • A 6-week study found low intensity stretching produced greater gains than moderate intensity. The control group stretched at ??% of their pain threshold and got ?????? results​
  • Low intensity means 30 to 40% of your pain threshold, genuinely relaxed, not straining, holds of ?? seconds​
  • Yoga practitioners had double the pain tolerance of non-practitioners when exposed to thermal stimuli
  • They also showed significantly more ????? ?????? in the brain region responsible for ??????????? why you're in pain​

​

​Gustav Söderström, Spotify | David Senra​

  • Almost 90% of Spotify users are pleased with the time they spent on the app. Users on Instagram and TikTok regretted ??% of the time they spent
  • We all have a type of content that hooks our attention every time, even though we feel worse after. For Gustav, it's ???? ???? ??????​
  • Platforms need better "??????? ???????? ?" tools that let users rid their content kryptonite from their feeds
  • Apple tried to kill Spotify many times. Spotify survived for three reasons: ????????, ?????????????, and ????????​
  • "You say to Spotify: I want a running playlist for an 8-minute mile. I want it in my taste. I want it on the ????????. And I want you to ?????? ?? ??????"
  • Spotify is using AI agents to deliver ??????? ???????? ???????? combining private information you feed it with public content you're interested in
  • "My principle is always be first. The world is going to change. Just accept that and ??? ????? ?? ??? ?????"

​Andy Stumpf: The Mental Frame & Specific Daily Actions to Succeed | Huberman Lab​

The concern vs influence exercise

  • Take a piece of paper, draw a line down the middle. Left side is CONCERN, right side is INFLUENCE
  • Write down everything occupying your waking hours and almost everything ends up on the left
  • The right side only ever has one real thing: yourself. Your thoughts, how you speak to yourself, how you manage your time
  • "I have no control over what happens to me in my life but I have absolute and complete and total control over how I respond to it"
  • Do this once a month, great to do on airplanes instead of doom scrolling
  • Social media has massively inflated the left column because your entire past is permanently attached to you unless you consciously cut it off

Two Navy SEALs vs their phones

  • Andy and Chadd Wright challenged each other in January to get phone screen time under 1 hour a day
  • Chadd never got below 90 minutes. Andy got down to 30 by moving everything to his laptop. Instagram on a laptop is so clunky you just close it and walk away, the stickiness is entirely the phone
  • "My mental health was better in January than it had been in a long time"
  • By March both of them had fully reverted. That is the whole point. Two guys forged in SEAL selection, competing against each other, still went back
  • The right question: is the platform working for me, or am I working for it?
  • What got teens off cigarettes was not health data. It was showing old executives laughing about the money they'd make off young smokers. The rebellion of youth turned against the platform is the only real lever

Do the slightly harder thing

  • Pick the slightly harder choice as often as possible. The small stuff nobody sees is what makes the biggest difference
  • Classic example: coffee cup in hand, sink is right there, dishwasher is also right there. One is slightly harder than the other
  • "How you do anything is how you do everything" is one of the mantras in the teams
  • The anterior mid-cingulate cortex actually grows in volume when you do things you do NOT want to do
  • This is the defining feature of super-agers, people who maintain cognitive and physical ability into their 80s and 90s
  • The growth only happens if the thing is something you genuinely do not want to do in the moment. If you love the ice bath, your anterior mid-cingulate cortex is not benefiting
  • Micro-discipline over a lifetime creates the appearance of macro-discipline. It is not the other way around

The hardest thing he has ever done

  • The divorce was the hardest thing he has ever done in his life, harder than anything the military ever put him through
  • SEAL training never made him question whether he was a good enough person to keep going. The divorce did
  • His oldest son completely cut him off for a year and a half. Andy kept writing letters, showing up, staying the course
  • Their relationship is now probably closer than it has ever been
  • He does not go into details publicly because he has a platform and his ex-wife does not. That is the fair call

The SEAL community and suicide

  • The SEAL community has now lost more people to suicide than to combat operations since 2001
  • Every instance Andy has been close to involved a very high performer, highly regarded, revered. That loneliness-at-the-top problem is real
  • The language people leave behind often includes something like "you will be better off without me," the irrational decision being framed as the only rational option
  • A lot of guys brought a full seabag of trauma before they ever entered the military. The more Andy has dug into this the more it is trending past 50% of the guys he knew
  • The military gets all the blame for why veterans struggle, but pre-existing trauma layered under the military experience is a massive and underaddressed part of it
  • Every time in his life he has actually told someone what he was going through and let them help, things got better. Staying quiet and toughing it out alone just meant suffering longer for no reason

​[Outliers] Chung Ju-yung: The Hyundai Founder Who Put a Country on His Back​

Running away from home

  • Chung was born in 1915 in what is now North Korea. His family farmed 3.5 acres to feed 10 people. In bad years they ate tree bark and grassroots to survive through spring
  • He ran away from home four times. His father caught him the first three and dragged him back
  • Third attempt: stole his father's cow, sold it for train fare to Seoul. His dad found out and crouched in the dirt and wept
  • The cow theft is not a story about wanting more. It is a story about guilt. He carried that debt for 65 years

His first auto repair shop

  • He bought an auto repair shop with a 30,000 won loan even though he had no idea how to fix cars. Other shops took 10 days per job. He averaged 3
  • A fire destroyed everything. He went back to his lender. The only way the lender would see his money again was to fund him again. The lender said yes
  • "There are trials, but there are no failures"

The Goryeong Bridge

  • Floods wiped out the scaffolding. Then hyperinflation hit. A sack of rice went from less than half a won to 41 won, nearly 100x, on a fixed price contract
  • His brothers all said stop. He refused. "Trust is everything to a businessman. The moment you lose trust, it's all over"
  • They borrowed more at 18% per month interest. Not per year. Per month
  • They spent more than twice what they earned. The government gave Hyundai the highest credit score of any construction firm in Korea specifically because they finished while everyone else walked away

Building the expressway

  • The World Bank said it was economically and technologically infeasible
  • Ministry of Construction estimated 65 billion won. Chung said 28 billion. Park asked if it could really be done at that price. Four words: "I can do it"
  • Hyundai bought 1,900 pieces of heavy equipment for one project. The entire country owned 1,400 at the time
  • He would inspect in the morning, leave, then come back unexpectedly. The standard should be the standard all the time, not just when the boss is watching

Time to start making cars and ships

  • Ford chose Hyundai and ended the interview in two hours instead of three days after Chung walked them through every part of a car from his decades-old memorized list
  • "I'll never take down a single Hyundai sign with my own hands. Quitting is not in my dictionary"
  • He carried three things everywhere to pitch ships: a photo of a deserted beach, a map, and blueprints for a 260,000-ton tanker. One detail he hadn't mentioned: they didn't own the beach. They bought it the moment the money came in

Crossing the DMZ

  • On June 16, 1998, at age 82, Chung led a convoy of 50 trucks with 500 cows across the DMZ into North Korea
  • Four months later he came back with 501 more. 1,001 total: one for the cow he stole from his father 65 years earlier, and 1,000 for interest
  • He built every single thing twice. The pattern was always the same: someone takes what you built, you build something bigger
  • "Diligence will overcome all difficulties"
