It’s true. From Teddy’s autobiography,
“While President I used to box with some of the aides, as well as play single-stick with General Wood. After a few years I had to abandon boxing as well as wrestling, for in one bout a young captain of artillery cross-countered me on the eye, and the blow smashed the little blood-vessels. Fortunately it was my left eye, but the sight has been dim ever since, and if it had been the right eye I should have been entirely unable to shoot. Accordingly I thought it better to acknowledge that I had become an elderly man and would have to stop boxing. I then took up jiu-jitsu for a year or two.”
Childhood is supposed to be inefficient. The unscheduled hours are where imagination lives, where boredom fosters creativity, and where kids learn to figure out what they like and don't like.
The parents booking every week of summer in February think they're being responsible and helping their child succeed. I think they're robbing their kids of their childhood.
I favor a lot of the classics, a lot from my childhood:
- The Velveteen Rabbit
- Go Dog Go
- Fox in Sox
- Peter Rabbit
- Robert Louis Stevenson
- Mother Goose’s nursery rhymes
- Charlotte’s Web
- Saint-Exupery
- Hans Christian Andersen
Any recommendations are welcome!
One of the funnest things about fatherhood is getting books for my son. Amazon just delivered a version of The Conference of the Birds. We haven’t read it yet, but it’s beautiful. Illustrated by Demi. #childrensbooks#fatherhood

Barbell strategy for killing it in an age of superhuman AI:
Simultaneously get as close to AND stay as far away from AI as humanly possible.
1. Get close — play with AI models, use them to help you think, ask them to teach you about the world, get them to help you create, work with them to write code, understand what makes them tick, embed them into your everyday life, have fun.
2. Stay far away — learn to tell stories, make eye contact, build a team, lead with courage, connect far-flung ideas, build lifelong friendships, debate persuasively, think forbidden thoughts, handwrite ideas, confess your fears, fall in love.
Spend less time trying to master mental transformations that are purely mechanical — building spreadsheets, analyzing trades, balancing accounts, writing code by hand, following playbooks, searching for needles in haystacks. These are the emerging no-man's land, squarely the domain of AI.
Venture to the extremes. That’s where all the fun is anyway.
Paying attention to birds — and doing so in whatever way is accessible to people — supports a person’s health. You’re not only moving around, but you’re listening; you’re noticing signs of birds, you’re enhancing your cognitive flexibility.

A mic drop moment @ycombinator tonight
@sama just offered $2M in OpenAI tokens to EVERY YC startup in the current batch in exchange for equity
Just like Yuri Milner offering to invest in every startup back when Sam was a YC partner
I can't wait to see what's unlocked when you let the most driven, creative and formidable founders tokenmaxx
¡Nieve en plena primavera! ❄️

It's not hard for an American man to be "Mexicanized."
You show up in the desert penniless, exhausted by the harsh sorrows of the world. You wander around Yuma. By chance, some friendly campesinos offer you some Tecate. You get drunk.
They offer you work picking lettuce, and you take it. Immediately, you're immersed in a world of cumbia and corridos, habanero salsas and tamales, great big crates of lechuga loaded onto trucks, and you're tanning so dark you're starting to look Mexican yourself.
The guys are calling you "güero" -- they're nice to you. They're nicer to you than anyone's been in years. They want you to play fútbol in the churchyard with them; they never exclude you from whatever they're up to, never skip you in the tequila rotation. Their world is colorful, loud, sweaty, laughing, and they're glad you're there. You get the sense that this is how it was always supposed to be.
And you can't come back from that. When you go back home, everyone seems so "stiff" and cold. Your family, they eat quickly, they don't linger over anything, they don't seem to enjoy anything. Your town has no one playing fútbol on the lawn, no cumbia, no burning sun that makes you smile and sweat. Everyone is awkward, tentative, distant. You cannot help but miss la frontera.
It's at that moment that the process is complete. You just can't go back. You're "spiritually Mexican" now.

Hong Kong: On March 23, 2026, the Hong Kong government changed the implementing rules relating to the National Security Law. It is now a criminal offense to refuse to give the Hong Kong police the passwords or decryption assistance to access all personal electronic devices including cellphones and laptops. This legal change applies to everyone, including U.S. citizens, in Hong Kong, arriving or just transiting Hong Kong International Airport. In addition, the Hong Kong government also has more authority to take and keep any personal devices, as evidence, that they claim are linked to national security offenses.
