P.S. You Should Know...
👋 Welcome back to P.S. You Should Know… probably the best newsletter published on Sundays between 6-7am CST, and definitely the best one published by me. Now in its fourth year!

my story 🚀
😍 Heart shaped glasses took over Petra's school and Daphne is now 3️⃣ months old!

📘 You may have noticed my book recommendations getting longer. I’m writing more to help process and remember key insights. I recently finished writing about Mindset by Carol Dweck.
Often we simply copy/paste beliefs of parents, teachers, friends, etc. Mindset, whether growth or fixed, tends to develop from our social environment rather than our deliberate choice. The problem? Research shows growth mindsets are simply more useful. So, if your childhood belief system instilled a fixed mindset, every passing day leaves you disadvantaged.
📚 Other recent book reviews: Benjamin Franklin: An American Life and Flow.
👨‍🎓 It’s been a full week of learning! Thanks to the Economic Club of Chicago, I heard Mondelez CEO Dirk Van de Put discuss his days running a pirate radio station in Belgium (full recording) and NBA Commissioner Adam Silver speak openly about the rough patch in NBA-China relations (full recording). I also learned from interesting professionals at the Kellogg Private Equity and Venture Capital Conference, including Sally Pofcher, the CEO who grew Paper Source from 20 to 100 stores. I’m grateful to spend time around such inspiring leaders and learn from their experiences.

fun facts 🙌
An archive of old military maps. Now digitized for our viewing pleasure, including the American Revolution and Napoleonic Wars. “George III’s collection of military maps comprises some 3,000 maps, views and prints ranging from the disposition of Charles V’s armies at Vienna in 1532 to the Battle of Waterloo (1815).” | learn more
Hunter S. Thompson’s schedule puts your worst bender to shame. “Below, you’ll find his daily drug schedule which was detailed in E. Jean Carroll’s biography, Hunter: The Strange and Savage Life of Hunter S. Thompson. As you’ll soon find, old mate Hunter was all about that bender life.” | learn more
oh, chicago 🏆
Peapod grocery delivery is leaving Chicago and the Midwest. Without retail locations for grocery pickup, they’ve struggled to retain customers. “A Chicago tech success story is abandoning its native home as companies like Instacart and Amazon provide what it couldn’t here.” | learn more
Are legal mushrooms coming next to Chicago? “A little over a month after Chicago made recreational marijuana legal, the City Council is considering whether to decriminalize what are termed “entheogenic” plants that contain psychoactive substances that can induce a spiritual experience.” | learn more
tech, startups, internet ⚡
Starlink is a big deal (possibly). Starlink is the network of satellites that Elon Musk’s SpaceX has started launching to provide global internet coverage. Jeffrey Paul, the author of this post, explains why it’s a big deal. I’m inclined to agree with him. One criticism, though: he ignores the many risks along the path to building the Starlink network. | learn more
Stratechery’s analysis of Visa’s acquisition of Plaid. Ben Thompson begins at the beginning: the rollout of Bank Americard (which would become Visa) in Fresno, CA in 1958. Not mentioned here, but interesting: Visa’s founder Dee Hock launched to 100k customers in 90 days – before the internet existed. | learn more
Remote gardening. An entertaining Kickstarter project, but nowhere near its funding goal. “Now you can grow and harvest your own produce from the comfort of your own customized App… A monthly subscription gives you viewing and watering access to your plot. You’ll select from a variety of pre-planned gardens or buy the seeds you need from our inventory to create your own custom layout.” | learn more
better doing 🎯
Good science, bad science, pseudoscience: how to tell the difference. “In a digital world that clamors for clicks, news is sensationalized, and “facts” change all the time, here’s how to discern what is trustworthy and what is hogwash.” | learn more
95%-ile isn’t that good. I imagine this is a controversial point of view. “Reaching 95%-ile isn’t very impressive because it’s not that hard to do. I think this is one of my most ridiculable ideas. It doesn’t help that, when stated nakedly, that sounds elitist. But I think it’s just the opposite: most people can become (relatively) good at most things.” | learn more
Why students forget everything on your powerpoint slides. This is written to an audience of educators, yet applicable to most of us. Basically, the redundancy of written + spoken content creates cognitive overload that leads to less learning. Instead of text, use graphs and images to complement the spoken content. | learn more
retail therapy 💸
Brandless shuts down operations. The best-funded online retailer that aimed to cut out brand premiums and sell everything direct-to-consumer has shut down. They had raised $290 million, mostly from SoftBank, but couldn’t get the economics of the business to work. Some of the investment was contingent, so while they ran out of cash, they didn’t burn through the complete $290 million. | learn more
Here’s what’s killing malls. Long before Amazon and internet retail, malls were already in trouble thanks to competition from big box stores. | learn more
under the microscope 🔬
A tiny brain implant wakes monkeys from comas. “…[T]he Wisconsin team used much smaller electrodes to precisely target the central lateral thalamus. They also designed the electrodes to match this region’s shape. When they flipped on the stimulation, it had an immediate effect on the monkeys.” | learn more
thoughts of food 🍔
The rise of plant-based plastic packaging. Seems the writing is on the wall for single use plastics, which is probably a good thing. “Alternatives to plastics are growing in popularity. Can they be scaled?” | learn more
Avocado pits used to make straws and cutlery. I used an avocado-pit straw at La Josie this week and it was much better than paper and the other plastic alternatives I’ve tried. | learn more
