Most people will read this and think optimists live longer because they eat better and exercise more. The study says something wilder.

Lee et al. controlled for smoking, diet, exercise, alcohol, depression, BMI, and socioeconomic status. The longevity effect still held. The most optimistic quartile lived 11 to 15% longer and had 1.5 to 1.7x odds of reaching 85 even after removing every behavioral difference.

Which means something is happening at the level of biology, not just habits.

Rozanski’s meta-analysis across 229,391 participants found optimists carry 35% lower cardiovascular event risk. Blackburn’s Nobel Prize-winning lab at UCSF found pessimistic attitudes are associated with accelerated telomere shortening. Cortisol suppresses telomerase, the enzyme that rebuilds the protective caps on your chromosomes. So chronic negative expectation literally erodes the structures that keep your cells from aging.

The loop runs: pessimistic cognitive style → sustained HPA axis activation → elevated cortisol → telomere degradation → accelerated cellular senescence. Optimists interrupt that loop at the top. They show less emotional reactivity to stressors, faster recovery from acute stress, and they default to reframing threats as challenges rather than catastrophizing.

The part nobody talks about from this paper: the authors explicitly state optimism is modifiable. This isn’t a personality trait you’re born with. Cognitive reappraisal training, morning sunlight for cortisol rhythm regulation, deliberate breathing protocols for vagal tone, structured gratitude practices. All of these shift the prefrontal cortex patterns that determine where you sit on the optimism spectrum.

A 35% reduction in cardiac events from a trainable psychological variable is a bigger effect size than most supplements on the market. That’s the real story buried in this abstract.

There's a formula for knowing when to stop searching and commit.

Works for dating, hiring, apartments, anything with a deadline.

Explore a portion of your options first. Then commit to the next one that beats everything before it:

- Looking for the #1 option? Explore 37% and commit to the next best one you see; 37% chance you get it.

- Fine with a choice in the top 3? Explore 26% and you land one 60% of the time.

- Fine with a choice in the top 5? Explore 21% and you get it 70% of the time.

A good choice now beats a perfect choice someday.

This is excellent. I highly recommend exploring it if you're interested in extreme longevity: https://t.co/9yRklnkmaO

The older I get, the more I think outstanding taste in people is the only real alpha.

Morgan Stanley dropping 20 years of quality investing lessons in one slide:

1️⃣ Pick great stocks, then let compounding run
2️⃣ Know what you own – opacity isn’t a dealbreaker
3️⃣ Judge management, not marketing narratives
4️⃣ Benchmarks mislead – error tracking beats comparison
5️⃣ Risk mgmt = absolute, not relative
6️⃣ What you don’t own matters too
7️⃣ Conviction deserves concentrated sizing
8️⃣ Valuation > earnings optics – focus on true FCF
9️⃣ Win over years, not quarters – find long-term holders
🔟 Stay curious, question everything, even yourself

A founder asked my advice about combining a startup with having small children. I told him family is more important than business, and to put his kids first and cram the startup into the remaining time.

Mochary believes in what he calls "cognitive offloading" - your EA becomes your second brain.

They manage all the details and follow-ups so your mind stays clear for the hard problems only you are uniquely positioned to solve.

But what's the need?

[Tim Ferriss @tferriss]

“What could possibly be more important than your kid? Please don’t play the busy card. If you spend 2 hours a day without an electronic device, looking your kid in the eye, talking to them and solving interesting problems, you will raise a different kid than someone who doesn’t do that. That’s one of the reasons why I cook dinner every night. Because what a wonderful, semi-distracted environment in which the kid can tell you the truth. For you to have low-stakes but super important conversations with someone who’s important to you.” — Seth Godin

Good morning Europe,

Let's get to work…

1) As some of you already heard: the EU has confirmed that they are starting to work on a pan-european legal entity early 2025 🔥

2) Instead of waiting and hoping for the best. We want to frontrun this and – together with the whole startup ecosystem – create the best 👀

Today we are opensourcing a first-draft of how the EU-Inc could look. And we want your contributions.

What are we missing? What's unclear? What edgecase might be an issue? The @euinc_petition needs you! 😉

It's all opensource and public here https://t.co/iaB7x3QglH

This first draft was created with several dozen legal experts in the European ecosystem. Now we are opening it up to the wider community.

We – as a community – got until January 15th to finalize a draft for the EU-Inc.

To contribute simply comment in the notion (seriously what could go wrong 😬) or use the feedback button to send us your thoughts/changes/suggestions/questions.

Please promote this and send this to your friends.
Ask your legal-council to give their feedback too.
Post on twitter your thoughts to give this more reach.

The last time we said "we got 6 weeks" we managed to make this an urgent part of the work agenda.

This time we got 6 weeks to make sure the implementation is right for startups.

Let's show, not tell! 🔥🇪🇺
