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!

📊 In our businesses, we make financial budgets and measure performance against them. When it comes to our time, though, we often spend without any accounting. Friday afternoon, I documented my ‘time spend’ by activity, tagged each activity toward one of my quarterly objectives or the fallback “other” category, then made a pie chart. It took about 20 minutes. It helped me see whether I’m allocating my most limited resource appropriately (I could do better). I’ll probably use this technique for another week or two and see if I still find it valuable. Have you thought about this challenge? I’d love to hear from you!

📙 The Upside of Stress by Kelly McGonigal (Psychology / Stress)
Kelly McGonigal preached the danger of stress to anyone who would listen. For many years. She was a health psychologist working to translate science into practical strategies for everyday life. In 2012 she abruptly changed her mind. McGonigal’s book, The Upside of Stress, challenges the narrative that people should avoid stress.

fun facts 🙌
Apple won’t let bad guys use iPhones in movies. I get why they’d have a strong preference here, but I’m surprised they have control at all. I mean – iPhones are everywhere! If any readers know the nuances here and care to educate me, I’m ready to listen. | learn more
Every possible melody released to public domain. “Damien Riehl and Noah Rubin generated and saved every possible melody to a hard drive, then turned it back around to the commons.” They hope to stop copyright lawsuits against artists. | learn more
oh, chicago 🏆
Joe Berrios must pay $168k in fines after all. The once-powerful (and now former) Cook County Assessor earned the fines from the county ethics board for illegal campaign contributions. He sued to claim the ethics board had no right to make the rules he broke, but the judge dismissed his complaint. Also, he’s under federal investigation for all sorts of stuff that I can best summarize as corruption. | learn more
tech, startups, internet ⚡
Technological Revolutions
Technological Revolutions
The deployment age. In this 2015 article, investor Jerry Neumann walks us through Carlota Perez’s framework on technological revolutions. “The wave that we are currently in, the Information and Communications Technology Revolution, started around 1971.” If we’re truly on the back-half of the wave now, post-bubble, it’s good to know the implication. | learn more
The risk of distributing risk. Lambda School is a startup programming school that uses income sharing agreements to tie tuition payments to students’ income (no income = no tuition). That leaves ‘accounts receivable’ stretching out for years, so they sell it off to outside investors for cash today. This has caused some to throw shade at them since the practice came to light. Ranjan Roy offers an interesting and nuanced analysis in his newsletter Margins. | learn more
better doing 🎯
40 powerful concepts. Rolled up into one page, this is a series of tweets by Gurwinder Bhogal describing important concepts with few words. Examples of concepts: causal reductionism, emergence, survivorship bias, concept creep, and streetlight effect (pictured above). | learn more
A conversation with Daniel Kahneman. This is the guy who pioneered research into human bias and is considered a father of behavioral economics. Now that bias is the talk of the town, he’s focused on another decision-making problem: noise. | learn more
retail therapy 💸
The Body Shop will start hiring the first person who applies for any retail job. In 2019 they used a first-come, first-served hiring policy in their warehouse. The result was a 60% decrease in monthly turnover. They’re rolling out the hiring policy to their retail stores this summer. | learn more
Walmart is working on a Prime competitor called Walmart+. Especially interesting: “Today, more than half of Walmart’s top-spending families are Amazon Prime members, according to sources.” | learn more
under the microscope 🔬
Stem cell therapy “functionally cured” diabetic mice. “One emerging treatment for diabetes involves converting stem cells into beta cells that secrete insulin. Now scientists have developed a more efficient method, and implanting these cells in diabetic mice functionally cured them of the disease.” | learn more
Power generation from ambient humidity. Yet another way to harvest clean renewable energy from our environment. “Here we show that thin-film devices made from nanometre-scale protein wires harvested from the microbe Geobacter sulfurreducens can generate continuous electric power in the ambient environment.” | learn more
More than 80 clinical trials launch to test coronavirus treatments. I find it interesting for two reasons. 1) The World Health Organization is getting involved to set standards for studies and promote good design like control groups and randomization. 2) Traditional Chinese medicine is being tested, which I appreciate because while it’s silly to blindly accept homeopathic treatments it’s just as silly to not offer them a fair trial. | learn more
thoughts of food 🍔
New York City may start regulating Grubhub’s fees. If this doesn’t earn an 🙄 and 🤦‍♂️, I don’t know what does. “The bills propose that food delivery apps be limited to charging restaurants no more than 10 percent commission, and require them to be licensed through the city’s Department of Consumer Affairs.” | learn more
The war on food waste is a waste of time. “Efforts to reduce the amount of food in landfills produce a lot of pretty infographics but very little change to a deeply flawed food system.” I had to hold my breath to get through some of the socialist-scented paragraphs, but the topic and viewpoint are intriguing. | learn more
big ideas 📚
A Federal Reserve of consumer data to fund basic income. From Rob May of Inside AI. “I’ve written a few times about basic income because I see it as a possible side effect of AI, automation, and possibly job loss. I wrote last year about why I think basic income may be a good idea, but that it is ultimately politically unfeasable, and would not recommend it. As I was reading the Economist’s special section this week on the data economy, I realized that there may be a path forward.” | learn more
on the blockchain ⛓
Blockchain-native insurer Nexus Mutual pays out. The insurance policies use tokens and are governed by blockchain voting and economics. There was recently a payout due to an attack on bZx. It’s interesting to see this take place with real money rather than crypto-economic theory. | learn more
