correlation vs causation?
Aakash Gupta@aakashgupta

Your morning coffee on an empty stomach is a cortisol bomb. Cortisol follows a natural rhythm. It peaks when you wake up, then gradually drops through the day. Breakfast is the signal that tells your body to start pulling cortisol back down. Skip that signal and cortisol stays elevated for hours past its normal window. Now add coffee. Caffeine directly stimulates your adrenal glands to produce more cortisol. So the actual sequence for millions of people every morning: wake up with peak cortisol, skip food, pour a stimulant into an already-stressed system, then wonder why they feel wired and anxious by 10 AM. The mechanism connecting this to depression runs through serotonin. Your brain synthesizes serotonin from tryptophan, but tryptophan needs insulin to cross the blood-brain barrier. Insulin comes from eating. No breakfast means no insulin spike, which means less tryptophan reaching the brain, which means less serotonin production during the exact hours your brain is trying to stabilize mood for the day. This study found the link is strongest in adolescents (51% higher odds of anxiety vs no significant link in adults). That tracks perfectly. Teenagers skip breakfast at the highest rate, sleep the least, and drink the most caffeine relative to body weight. Three compounding cortisol drivers stacked on a brain that's still developing its stress regulation systems. 399,550 people across 14 studies. The finding isn't that breakfast is magical. The finding is that your body uses that first meal as a hormonal reset button, and skipping it leaves your stress system running in the background all morning like an app you forgot to close.

The 6 characteristics of an entrepreneur: 1. The entrepreneur keeps himself operating on the threshold of excellence because he fears mediocrity. 2. The entrepreneur has learned to dig for facts. The first explanation given does not include all the facts. Once the facts are found, the necessary action is clear. 3. The entrepreneur has a sixth sense of what will work and what will not work – by adjusting experience and knowledge. 4. The entrepreneur tenaciously grasps every opportunity to meet goals using the art of human relations (some say it is a science), the laws of the marketplace, and excellent management of manpower, money, and machines or resources. 5. The entrepreneur knows that he must delegate responsibility, but he never sacrifices his knowledge of the details. 6. The main difference between the entrepreneur and the manager is attitude!

A sign of emotional intelligence is the ability to laugh at yourself. 6 studies: After making small mistakes, people are seen as warmer and more capable if they're amused instead of embarrassed. Taking your responsibilities seriously but your ego lightly is a core life skill.

A few geniuses solve problems and automate solutions for the rest of society. Any society that can overcome envy to maximize the number and output of geniuses will thrive.

22 Tiny Lessons from my conversation with Nicolai Tangen. 1. The faster you reply, the less you need to say. If you reply in a minute, you can say two words. If you wait a day, it’s a paragraph. 2. Overanalyzing doesn’t improve the outcome. It just makes you more confident about the outcome. 3. “If you have really high ambitions, you achieve great things even if you fail. If you have low ambitions, you achieve nothing even if you succeed.” 4. “You call it gut feel, nobody believes in it. You call it pattern recognition, a lot of people believe in it.” 5. Repetition is persuasive. 6. “Why make the same mistakes when there are so many to choose from? Find some new ones.” 7. Take the same amount of risk after a win and a loss. 8. “Things shouldn’t take longer than they need to take.” 9. Doing nothing is often the best option. 10. Speed and agility are the only hedge in a world you can’t predict. 11. Be impenetrable against social pressure and instant in responding to evidence. 12. The people who feel weird, different, and misunderstood are the ones who change the world. 13. Changing a culture is a ten-year project. If you think you’re halfway done in two, you haven’t started. 14. Asking for advice makes people think you’re smart because you are clever enough to recognize how clever they are. 15. “If you’re not curious, you’re not going to listen.” 16. “I would inject AI everywhere. I would just go all in.” 17. “It’s difficult to find people who are really contrarian now because you need to live in a space where people don’t agree with you.” 18. “You don’t have to be disliked even though people disagree with you.” 19. You can’t please everyone. Even if you are right, 10% of people will disagree with you. 20. The source of most of our poor decisions is blind spots. 21. “I don’t think you should profit from people who have a tough time.” 22. “Wealth is basically created by owning one or two really good assets, and then you just hold onto it for the very long term.” Listen and learn.

My conversation with @NicolaiTang1 Tangen runs the world's largest sovereign wealth fund and sees AI as a once-in-a-lifetime inflection point. He is responsible for managing $2.1 trillion. That's roughly 1.7% of all listed companies on Earth. This episode is full of surprising insights. Enjoy! (Includes paid promotions)

FDA formalizes its shift to requiring only one pivotal trial (via NEJM) and analysts are already pointing at companies this could help -- another pro-pharma push for Makary, and another 180 for Prasad who wrote extensively in his academic life against trials focusing on anything less than overall survival endpoints.news/fda-formalizes…

Some might say the Sky(rizi)’s the limit when it comes to pharmaceutical sales. AbbVie is generating more money now from its immunology drugs than it was when Humira was the best-selling medicine on the planet. Learn more. trib.al/uk930Kp
