LM: #355: The underrated impact of small projects

February 16, 2026

We all want to do something big, so few of us consider the value of small projects.

It seems pointless to:

Nothing big could come from any of those.

The value in small projects isn’t in the projects themselves, but in what they unlock:

If you keep putting off the big thing, take on a small thing, instead.

Book: The Instruction Of Ptah-hotep and The Instruction Of Ke’gemni (Amazon) are the oldest books in the world.

Cool: The SanDisk Extreme (Amazon) is a rugged and portable 1TB external SSD drive, perfect for video editing.

LM: #354: The sunk costs fallacy is the unlocked gains reality

February 09, 2026

I’m skeptical of the sunk costs fallacy.

It goes like this: Imagine you’ve bought tickets to an outdoor concert. The night of the concert, it’s cold and rainy.

You reluctantly go to the concert. But if you hadn’t bought tickets, and your friend offered you one for free, you wouldn’t have gone.

You only went because you had the “sunk costs,” but your preference if you hadn’t bought tickets reveals you didn’t want to go that badly.

I get the sense that the sunk costs fallacy is in itself a fallacy.

I submit: The unlocked gains reality.

The unlocked gains reality applies very well to creative projects. When you’re in the midst of a big project, it’s normal to consider quitting. I considered quitting my current book many times.

Yes, we’re reluctant to quit because we look back on all that work and don’t want it to go to “waste.” But we’re also reluctant to quit because we’ll never see any benefit until we get to an “unlock.”

You can’t sell your novel if you don’t publish. You can’t see if that reel takes off if you don’t post. In any creative project, you must reach some point before you can unlock the benefits.

You might choose to scale your project down to get to that unlock, but just because you have sunk costs doesn’t mean you’re foolish to persevere.

Like many things in economics and even behavioral economics, the theories expect us to know the future. It might not rain so much at the concert or with some preparation you might not be so cold, and you will likely enjoy it more than you imagine from the warmth of your home.

The same applies when you’re in the shit and want to quit. You can’t get the gains until you reach an unlock.

LM: #353: What I’ve learned from Leonardo da Vinci

February 02, 2026

I heavily studied Leonardo da Vinci while researching for my upcoming book, Finish What Matters (tomorrow is the last day to buy the Preview Edition).

Besides the many fascinating anecdotes in the book, what I’ve learned about how Leonardo thought:

It’s easy to remain mystified by the illustrations, paintings, and myths, but Leonardo was just a man, and he had real ways of being we can all apply.

LM: #352: Extraordinary luck is ordinary

January 26, 2026

It takes luck to make it as a creative, but not as much luck as it seems.

I think it can be explained by what I call the “Travis in Tokyo” effect. At some point, you may have been traveling, and run into a friend. It’s a shocking experience, and you say, “What are the odds I’d run into my friend Travis in Tokyo?!”

There are a few phenomena that make this less exceptional than it seems.

One is ad-hoc analysis. You didn’t form a hypothesis before going to Tokyo whether you’d run into Travis. A lot of other surprising things could have happened. Scientists run into problems when they look for patterns in large data sets, finding surprising things such as that as cottage cheese sales decline, so do babies named Andrea.

Another is the multiple comparisons problem, which is that when a lot of different things have low odds of happening, at least one of them is likely to happen. You were surprised to run into Travis in Tokyo, but didn’t reflect on the odds you’d run into at least one of the hundreds of people you know.

Finally, there’s the fact that you’re friends with Travis and everyone else because you have things in common – perhaps an interest in Japan or travel, or just that you’re in the socioeconomic profile of people who would travel to Japan.

When we look at the success of a creator, and the chain of events that led to that success, we get tunnel vision as we consider the outrageously-low odds that chain of events could have occurred.

But we don’t consider that out of the many things they tried, this was the one that worked; that when adding up the low probabilities of their many attempts, the probabilities weren’t as low as they seemed; and that as skill and network effects compounded, those odds climbed with each attempt.

There is hope.

LM: #351: New Year’s estimates (not resolutions)

January 19, 2026

New Year’s resolutions are destined from the start to fail.

How could you possibly decide how many subscribers you’re going to gain, or weight you’re going to lose?

Even if you stick with what you control, how could you go from not doing a behavior at all to doing it regularly? You don’t even know what it’s like and you and the world will change within the year.

It’s like trying to hit a moving target with an arrow made from a wet noodle.

This is why I prefer New Year’s estimates, not resolutions. Such as:

You don’t have the information to say what will happen, or what goals will still be worth striving towards. By making an estimate, you give yourself a chance to respond to reality.

There’s also something about making estimates that makes you think about reality: Resolutions are aspirational. By saying this will definitely happen, you paradoxically shut yourself off from the factors that will affect whether it does.

As you think about whether something is 50%, 70%, or 90% doable, you start to think about what’s actually affecting your ability to make it happen, which often leads to thinking of actions you can take to increase your odds.

Aphorism: “The present of things past is memory; the present of things present is sight; and the present of things future is expectation.” —Saint Augustine

Book: Paul Millerd’s $100 Pathless Path Hardcover is quite beautiful, and an inspiring publishing experiment.

P.S. Making and reflecting on estimates is a key tactic in my upcoming book, Finish What Matters. There’s still time to start reading the Preview Edition.

LM: #350: The dopamine channel

January 12, 2026

A dominant meme of the early internet was that we were freed of the era of “three channels” – when the American television airwaves and thus psyche were controlled by ABC, NBC, and CBS.

But now it feels like we have only one channel.

That’s of course not materially true. We’re free to dig up anything we want, unlike ever before. But “channel” implies passivity, which is what TV was, and what we’ve reverted to.

Another meme about the dawn of the internet was the removal of “gatekeepers.” Finally, the ideas would spread that were the most interesting – about the most obscure topics you could imagine.

But what we’re being offered up feels strangely “smooth.” The topics might be different, but the depth, pacing, and structure falls within a tight range, like all the rough edges have been sanded off.

The smoothness, of course, is from “the algorithm.” We might as individuals appreciate the jagged edges of something, but can the algo mathematically sniff out everyone else who does? It seems not. And now LLMs are mathematically deciding which word would be most likely to come next, and changing it just enough that what comes out is essentially the same thing.

And maybe those gatekeepers made things a little less smooth, a little more jagged. We didn’t like how this person or that got this big break through nepotism or sexual favor, but some of it must have been from the mere whim or strange taste of some executive. In any case at least something that didn’t “deserve” the exposure in the algorithmic sense got it, and there was probably something good about that.

Because we used to have three channels, and now we just have the dopamine channel.

LM: #349: What I stumbled across meditating 365 hours

January 05, 2026

As 2025 began, I made a soft agreement with myself to try to meditate 300 hours in the year. I’d try an hour most days, and figured I’d miss a day here or there.

Now I’ve meditated an hour a day more than 365 days.

In the past, I deliberately avoided holding a streak – I purposefully quit my first hour-long meditation challenge after 89 days, to avoid the psychologically-significant “90.”

I’ve been holding onto this streak mostly because not meditating now feels like not brushing my teeth, or not sleeping. I get so much out of each session, I don’t want to miss it.

By far the biggest revelation has been my accidental discovery of something I guess they call “somatic release.” I started feeling the urge to lean into tension in my face and body, leading to some strange facial expressions and postures.

It looks and is simple, but I have to warn that the tension patterns it releases have been very deep. I could see how it could really mess someone up mentally and physically. The first weeks after unlocking this I felt very shaky and emotionally fragile. I had severe hip pain – I thought I had uncovered a latent injury. So try at your own risk and maybe there are professionals you could consult?

Now I’m glad to have worked through that initial phase. I feel far more emotionally resilient. I get less angry, feel less insecure, and take things less personally. It shouldn’t be a surprise that also makes me feel a bit less ambitious – at least in my previous understanding of ambition. But in my writing I feel more capable of seeing an idea or feeling from all possible angles to really find the contours of what’s interesting.

The best way I can describe this process is as like sorting through a library of memories of not just the worst things that ever happened to you, but also the thousands of tiny moments of discomfort that pile up and get “stored” in your body. It also feels like sorting through experiences you haven’t personally had, but that are locked into the human nervous system through the experiences of your ancestors. Sometimes it’s accompanied by the actual emotions, but a lot of times it’s like you’re “acting” the emotions – such as by shedding tears but without sadness.

During each session I release a lot of this tension, but the next day there’s always still more to work through. Maybe someday it will all be gone.

If there’s any one revelation this far into this process it’s that all the emotions are okay: rage, humiliation, lust, elation, self-pity, and more. Many are not justified, but they are okay, a product of being in a human body. Few are worth acting on, but all are okay to feel, at least for that hour.

I wish more people had an hour a day to meditate, because you reach a point where it’s like driving with a new windshield.

Book: Slow Productivity (Amazon) is Cal Newport’s manifesto for knowledge work at a sane pace, which Mind Management lovers will enjoy.

LM: #348: Ode to the cheapest tools

December 29, 2025

This may feel too obvious to mention, but I can’t get over how some of the most valuable things can be made with the cheapest tools.

Larry David and Jerry Seinfeld wrote the most successful television show ever with BIC pens on yellow legal pads. (If you want to take it really far, Socrates just talked.)

So I find it entertaining to try to find the cheapest possible paper and pen. It is just so damn cool to me that I can use them to write a book that sells thousands of copies, or write the script for a reel with millions of views.

The cheapest I’ve found yet is 10 BIC pens for $1.29 (when I bought them 6 months ago, at least), and a 200-page notebook for 3,800 COP (~$1) at a neighborhood papeleria.

There’s definitely something to be said for a nice pen and paper, especially when you’re looking for a reminder that your thoughts are valuable, and worth writing down.

But this exercise does something else for me. I think it spreads to other areas, where next time I’m thinking of buying a new camera or audio equipment, I tell myself to snap out of it. Using cheap tools reminds you not to be too precious – that you’ll have to do a lot of work to get good at the stuff that matters, and that – maybe this is uncomfortable to admit – you already have what you need to get started.

Aphorism: “To one who can understand reason, you will find ten who admire wit.” —Maria Edgeworth

Cool: These acoustic blankets pack a lot of sound-dampening into simple (but heavy) blankets.

P.S. A tool that is perhaps even cheaper in the long run and very much still worth writing on is a typewriter.

LM: #347: The humanities are the science of being human

December 22, 2025

We wouldn’t want a plane engineer to forget the laws of physics. We wouldn’t want a doctor who rejects the fundamentals of biology.

But the scientific method which has gained us this knowledge seems to distract us, like a magician’s sleight-of-hand preventing us from seeing the rabbit under the table.

There have been times and places when the burning questions amongst the smartest people were not as much about what could be precisely measured and reduced to a formula – Ancient Greece, Renaissance Florence, Early India and China.

The questions were instead about what is a life well-lived, what trade-offs should a society make, and how do you navigate consciousness and this existence of fortune, desire, suffering, and elation?

None of these questions have concrete answers, which is understandably frustrating in a world where we have a name for the protein that causes this or that heretofore mysterious malady.

But it’s strange that people sat around and asked these questions, figured out and recorded pretty-good answers that are freely available to us, and most of us just struggle through life only to, if we’re very lucky and live a long time, come to the same conclusions the hard way.

Aphorism: “Is the resolve to be so scientific about everything perhaps a kind of fear of, an escape from, pessimism? A subtle last resort against – truth?” —Friedrich Nietzsche

LM: #346: In defense of over your head

December 15, 2025

We jump into projects because we think they’ll go well. They seem to always be more difficult, less fun, and take longer than we had expected.

This is one reason we get stuck in a cycle of starting, abandoning, starting, abandoning, without ever finishing.

But I’m beginning to think this is as much a feature as it is a bug.

One of the things I appreciate about ChatGPT is it gives me the confidence to take on projects, thinking it will do most of the work. They still end up being difficult, but I wouldn’t have bothered otherwise.

And as I reflect on my own career, I realize there is nothing I’ve created I’m proud of to which the meme doesn’t apply: We do this not because it’s easy, but because we thought it would be easy.

So I do what I can to avoid drowning: Make and review predictions, ask myself what I might not be thinking of, and conducting little experiments to test my theories.

But there’s ultimately something motivating about getting in a bit over your head. It forces you to learn to swim.

Aphorism: “Who is it that, seeing the havoc of these civil wars of ours, does not cry out, that the machine of the world is near dissolution, and that the day of judgment is at hand; without considering, that many worse things have been seen, and that in the meantime, people are very merry in a thousand other parts of the earth for all this?” —Montaigne (1575)
