Happy All the Time?

One of my wife’s favorite books from growing up was Happy All the Time by Laurie Colwin. It stands proudly on our bookshelf like a little totem to childhood optimism—a promise that somewhere out there, happiness could be a permanent state if you just figured out how to arrange your life correctly.

For a very long time, I believed that too. I even had a section on my website called “Happiness and Inspiration.” I thought that if I read enough, optimized enough, meditated enough—whatever the adult equivalent of eating my vegetables was—I could eventually arrive at happiness.

But this year, I realized I was chasing the wrong goal.

From Sapiens to Silicon: The Evolution of Storytelling Species

I think I’m the most special person on earth—part of the most special species on Earth. Not because of my job or my talents or anything I’ve accomplished, but because I’m human. And if you’re reading this, you probably think you’re the most special person on earth too—for the exact same reason.

But what really makes humans special? According to Yuval Harari’s Sapiens, it’s not tool use—crows can bend wires into hooks. It’s not language—whales sing and bees dance. It’s not even raw intelligence. What sets us apart is that we can believe in things that don’t exist, and then build entire civilizations on top of them.

Seventy thousand years ago, we were evolutionary middle-managers. Not the strongest, not the fastest, not even the smartest animals around. We were just… adequate. Then something extraordinary happened—what Harari calls the “Cognitive Revolution.” We learned to tell stories and, more importantly, to believe them together.

Evolution’s Bug Becomes a Feature

What gave humans the ability to tell these stories? Bigger brains. The kind that could handle abstract thinking, symbolic reasoning, complex language. But at some point, our brains got so large they created a problem evolution had never faced: they literally wouldn’t fit through the birth canal.

We had to be born early, before our brains could fully develop. Human babies arrive half-finished, completely helpless, but infinitely programmable. A gazelle can run within hours of birth. Human babies can barely hold up their own heads.

This seemingly terrible design—a brain that devours 20% of our energy and takes decades to mature—became our species’ superpower. It’s what lets a caveman’s descendant become a medieval peasant’s descendant who becomes a modern computer programmer, all without changing a single gene. Same hardware, completely different software.

The Invisible Infrastructure of Civilization

Walk around any city and you’ll see the infrastructure: roads, power lines, water mains. But the real infrastructure—the stuff that actually holds it all together—is invisible. It’s made of stories.

Consider Apple Inc. You can’t touch Apple—it’s not a physical thing. It’s a legal fiction, a story we’ve agreed to tell about ownership and corporate structure. Yet this imaginary entity employs 150,000 people and moves more money daily than some countries see in a year. The story of “Apple” has become functionally real through collective agreement.

Nations work the same way. The border between New York and New Jersey exists nowhere in nature—it’s a line we’ve drawn on maps and in our minds. But people organize their entire lives around it, pay taxes because of it, even fight wars over similar invisible lines.

Human rights might be our most beautiful fiction. There’s nothing in the laws of physics that says humans deserve dignity or freedom. But we’ve collectively decided to believe in these concepts, and that belief has toppled governments and reshaped the world.

Silicon Storytellers

Now we’re trying something unprecedented: we’re teaching machines to tell stories.

Instead of neurons firing in skulls, it’s synthetic neurons firing across vast server farms. Instead of culture gradually shaping a child’s mind, we’re using training data to shape artificial minds in mere months.

And what emerges is not just smarter calculators or faster search engines. We’re building storytellers. Systems that can spin up convincing worlds, simulate human voices, and generate fictions that ripple outward into real consequences.

These aren’t tools in the old sense — hammers and plows that rest when we put them down. They’re more like co-authors we’ve set loose: storytellers who never sleep, never age, never forget.

Reprogramming Ourselves

It’s unsettling to realize that the truths at the center of our lives—money, nations, even identities—can be mirrored so easily by AI. But that realization also gives us enormous power.

First, it reminds us that the stories we tell about ourselves are just as flexible. I am the kind of person who always fails at math. I can’t change careers this late in life. These aren’t biological limits; they’re personal fictions. And like any fiction, they can be rewritten. Psychologists call this psychological flexibility—the ability to observe our internal narratives as constructs rather than absolute truths, and to consciously choose whether they still serve us.

Second, it shows us how much our attention really matters. Every belief system runs on attention—from religions to social media platforms to the voice in your head that won’t shut up at 3 AM. You can see this most clearly online: your feed isn’t some neutral window on reality. It’s shaped by what you click, what you linger on, what you reward with your time.

This principle extends everywhere. You don’t need to track every market swing or breaking news alert. You can choose where to invest your mental bandwidth. That story that you “should be” doing something else, feeling bad that you’re not more productive? You don’t need to listen to it.

Here’s the thing: attention is a finite resource. Shift how you spend it, and you’re not just curating your information diet—you’re curating your reality.

Let’s Have More 3 Day Weekends!

Isn’t it great to have a three-day weekend? We have a little extra time to breathe, sleep in, maybe go somewhere. We should have more of them.

But there’s nothing we can do about that… right?

Well—maybe. Unless we were more like China. In China, they noticed the same problem: people want longer holidays. More specifically, the tourism industry wanted longer holidays, but businesses don’t want to give up too many workdays. So instead of fighting about it, they rearranged the calendar.

In 1999 , they invented something called 调休 (tiáoxiū)—”adjusted rest.” It’s a system of make-up working days, where weekends are sometimes converted into regular workdays called “special working days” to create longer blocks of time off around major holidays.

And you know what? It’s absolutely brilliant. And also completely insane. Let me explain.

What China Actually Did (Calendar Tetris, Government Edition)

Picture this: Next Tuesday is Dragon Boat Festival—a nice little one-day holiday. The government is so nice that they even give you Monday off to connect it to the weekend. Then your Chinese colleague casually mentions, “Oh, by the way, we’re working this Saturday to make up for it.”

Wait… what?

This is adjusted rest in action. China takes their holidays and engineers them into blocks by borrowing weekend days. That three-day weekend you’re enjoying? You may have worked a Saturday or Sunday to “earn” it.

It happens all the time throughout the Chinese calendar. Here’s the 2025 Chinese calendar. Note the special working days.

Why It Worked in China

This system works in China because of something you see everywhere there: an almost supernatural ability for society-wide coordination around shared priorities.

Take gaokao (高考), China’s college entrance exam. The entire country comes to a standstill for three days in June—construction sites go silent, airlines reroute flights, and businesses turn down music. It’s not just government policy; it’s collective buy-in because everyone understands this matters.

The same cultural DNA makes adjusted rest work. When the government says, “We’re all working Saturday so everyone can have meaningful family time,” there’s immediate social consensus. Chinese workers embraced this system because it delivers what they genuinely value: real time for family visits across this massive country. When your parents live 1,000 miles away, a single day off is useless. But a week-long Chinese New Year break? That’s life-changing.

When Beijing publishes the holiday calendar each October, 1.4 billion people simply adjust accordingly. No endless debates, no union disputes—an entire civilization synchronizes like a coordinated dance.

Why It Would Never Work in America

Now imagine trying to implement a make-up day policy in the United States. It would be chaos.

It doesn’t work for us because we’re too beautifully, chaotically diverse. Just think about all the observant Jews who can’t work on Saturday for religious reasons. Or the millions of retail and service workers whose schedules are already scattered across seven days a week. Or the parents juggling childcare around school schedules that don’t align with federal holidays. Or the freelancers and gig workers who don’t even have traditional weekends to begin with.

We’re just not the type of society that’s good at making collective decisions, even when they’d benefit everyone. Try to get Americans to agree on synchronized vacation schedules and you’ll trigger the same cultural immune response that makes us argue about daylight saving time for decades without ever actually changing anything.

What We Do Instead

So what do we do in the US instead? We move the holidays. That’s why most federal holidays that fall on weekends get shifted to the nearest Monday, creating automatic three-day weekends without anyone having to work extra days. It’s a far simpler and more elegant solution for our individualistic culture. No make-up days, no synchronized scheduling, no arguments about who has to work when. When Washington’s birthday falls on a Wednesday, we just shift it to the nearest Monday.

The trade-off? We don’t get those spectacular week-long vacation blocks that China engineers. Our longest federal holiday weekend tops out at three days. But for a country that can’t even agree on what to call carbonated beverages, maybe that’s about all the coordination we can realistically handle.

The Cafeteria Conspiricy

Voronoi diagram of people enjoying a park from Kottke.org

The strangest thing happens to me when I visit the cafeteria at work. People will come in from out of town and we’ll go to lunch with about 10 people. But there’s nowhere that we can find for 10 people to sit together. There will be a number of seats in a row and then one or two people there to break it up.

It’s like everyone is intentionally spreading out across the room as far as they can. It feels like there’s a conspiracy to keep us from finding a table.

The Truth Will Set You Free—But It Might Make the World More Boring

There’s something about folk stories behind names that makes the world feel richer. Names, after all, aren’t just labels—they’re little windows into the past, into the way people once understood the world. And when the official explanation is dry, people fill in the gaps with something better.

Skin in the Game

Making good decisions isn’t easy, especially when it’s hard to know what information to trust. In an ideal world, we could trust the information we hear from friends and from the news. But the media likes to cover the rare and shocking, not the common and routine. A plane crash halfway around the world (a highly uncommon occurance) can seem as likely as a car accident down the street. This distortion skews our perspective, creating a big gap between what we think is likely and what actually is.

Nassim Nicholas Taleb has a smart way of knowing what really matters—he calls it “Skin in the Game.” In his book by the same name, Taleb explains that people with something at stake usually offer the best information. It’s simple: when you stand to lose, you’re going to think carefully. But when you’re insulated from the consequences, it’s easy to toss around advice or make bold predictions because they sound good, not because they’re giong to work.

Why We Buy Overpriced Things and “Like” Things We Don’t Really Like

In economics we learn that as prices rise, demand falls. This happens because we assume that rational customers are looking to buy things that provide the most value for the least expense. But there’s a class of goods that don’t behave this way: Velben goods.

Veblen goods defy classical economics. Named after Thorstein Veblen, an American economist, these products become more desirable as they become more expensive. These goods are more desired not from the needs they fulfill but from their ability to signal status, exclusivity, and wealth.

Hacking Evolution: Fitness Faking

Animals can fake their evolutionary fitness in a number of ways. Humans do it too. While this may seem like we’re corrupting our gene pool it might not be so bad.

Looking at Fast and Slow Thinking on Facebook

I saw the following question on Facebook:

“I’m getting married, and my husband and I are looking at what our married name should be. My last name is Lipsky. It was changed by my ancestors from the original ‘Lipszyc’ when they immigrated to the US in the early 1900s. I’m starting to really connect with my heritage. Should I keep the current name or switch back to the previous name?”

What a Wonderful Word

Note: You can watch the speech I gave based on this material here.

I remember the first time it happened to me. It was the first year of business school and we were working on an economics problem set. My friend Yugin had just arrived from Korea and she was correcting an answer for her economics homework.

She asked me “What’s the English word for after you erase something?”

I thought this was a philosophical question like, “What’s left of an image after you remove it?” Something like the way Robert Rauschenberg erased a drawing by William de Kooning to push the boundaries of art.

So I answered, “When you erase something there’s nothing left. You’ve erased it.”

“No, that’s not what I’m asking. Those little pink things that come off the eraser. What do you call that?”

“Hmmm … eraser shavings maybe. We don’t have a word for that in English.”

“Huh,” she said, “that’s odd. We have a word for that in Korean.”
