There's only so much you can consume in a day. The supply of content has exploded. Most people haven't adjusted. Curation is now the skill that matters most. Here's how I'm approaching it:

Interesting ad campaign. Did not expect to run into an AI parody video of Kim Jong Un when I walked into Equinox today. Slop is everywhere.

Each New Year begins with the bluefin tuna auction at Tokyo’s Toyosu fish market, where the winning fish is said to bring good luck. This year shattered records: a 243kg tuna sold for $3.2M to Sushi Zanmai, marked once again by its founder’s iconic big smile and open-arms pose. Perhaps you’ll get a bit of that luck eating it at one of their locations. The chain recently opened its first U.S. location in Los Angeles.

AI compresses output. Meaning comes from the struggle, judgment, and journey behind the things that last. I wrote about mastery, process, and what AI can’t replace:

2025 was abundance. 2026 is the correction. Scarcity returns, not because we create less, but because we choose more carefully. My predictions for what becomes scarce: physical data, trust, authenticity, health, energy, taste, time. In an age of infinite output, the scarcest thing is knowing what matters to you.

Nothing hits like a pastry from a Parisian bakery 😋 This Pain Suisse is from one of my favorites, Du Pain et des Idees. What’s your favorite bakery in Paris?

Check out Ken Boswell (1972 NYN). He hit 0.211 with 9 hr and 2 sb, a 0.8 Player Value on DatabaseBall! 🏆⚾

I recently wrote about the history of saunas and onsens in Japan and Finland, and how they contribute to longevity and happiness: https://paragraph.com/@onchain-living-tjkawamura/the-power-of-heat-lessons-from-japans-onsen-and-finlands-sauna Just a few days later, The Wall Street Journal published a piece on the growing popularity of saunas in the U.S., highlighting their social and health benefits: https://www.wsj.com/lifestyle/workplace/sauna-othership-bathhouse-altar-cedar-and-stone-new-york-16b7ab8b It is exciting to see these traditions gaining traction in the U.S., both for wellness and as new social spaces. Who is a fan of saunas out there?

Doubt America has the attention to detail to ever replicate the convenience store magic in Japan. But I do have hope for egg sandos, fried chicken, and onigiri on every corner someday. 🙏🍙

Saunas in Finland. Onsens in Japan. 🧖‍♂️ Two ancient rituals, worlds apart yet both tied to health, happiness, and longevity. I wrote about what these traditions can teach us today.

Nvidia reported earnings yesterday. And just days ago they unveiled Jetson Thor, a robotics supercomputer. The signal is clear: the next breakthroughs in AI will not come from bigger language models or more web scraping. They will come from real-world data. This is Physical AI. 🔗

Love seeing more Japanese F&B brands enter and thrive in the US. Just stopped by “I’m Donut?” in Times Square and luckily there’s no crazy line like there is in Tokyo.

What if your startup treated customers like superfans, not just users? The Savannah Bananas turned a baseball team into a $50M business with zero ads and a 2M+ person waitlist. Here’s what they did differently and what founders can learn:
