Why Your Morning Coffee Isn't Working (unless you are Marc Andreessen)

Most energy drinks just dump caffeine in your system to block adenosine. You feel alert for a bit, then your cortisol spikes and you crash. Not ideal.

Better move: pair caffeine with L-theanine. It promotes alpha-wave activity, which means you get the boost without feeling like you're vibrating. Matcha does this naturally: slower uptake, fewer jitters, steadier focus throughout the day.

Here's what actually helps:

  • Citicoline keeps your attention sharp
  • Bacopa helps with memory (takes a few weeks to kick in)
  • Lion's mane supports nerve growth (still early research, but promising)
  • Rhodiola and cordyceps help you handle stress without frying your nervous system

Add some turmeric and vitamin C to deal with oxidative stress. B-vitamins keep your cells running...

The best ready-made formulation I've found which achieves this and more is Magic Mind, it packs all of this into one shot (matcha, L-theanine, nootropics, adaptogens, the complete package). It's designed for mental performance without the crash or the pill fatigue.

​The World From Another Point of View | Richard Feynman on Yorkshire Public Television 1973​

Physics is the only field that doesn’t seem to recognize the evolution of knowledge

  • Biology recognizes how different species came to be
  • Physics says “here are the laws” without mentioning ??????​

What really makes up the world around us?

  • “Nature is no doubt simpler than all our thoughts about it now. The question is what way do we have to ?????? so that we understand its simplicity. That’s where we stand now.”

The universe is strange, but the rules are ?????? — there are just sooo many ??????​

  • “There’s so much distance between the ?????? and the final phenomena that it’s almost unbelievable”
“When we get stuck in a certain place, it’s a place where history will ??????”
  • Measurements, symmetries, and mathematics are limited to the world we currently understand
  • “If all those methods would have worked, we would have ??????”
  • “The real test in physics is ??????and history is fundamentally irrelevant”
  • “It’s the cases that fail that are the interesting ones”
“What today do we not consider part of physics which may ultimately be part of physics?”
  • Analogy: A man searches for his lost keys under a street lamp because that is where he can see. After a few minutes, he concludes the keys aren’t there, but the problem is not that the keys don’t exist. The problem is that he is limited by ??????. The street lamp represents our current understanding of physical laws, and the keys represent the truths about ??????. Scientific progress often comes from having the courage to search beyond the places where our current knowledge ??????​

​Big P vs. Little P Purpose: Why You Don’t Need to Find Your One True Calling | Jordan Grumet on The Art of Manliness with Brett McKay (#1128)​

Big P Purpose often comes with anxiety and pressure

  • Big P purpose is the idea of one grand goal or “why,” something audacious and world changing you’re supposed to discover
  • Little P purpose is just doing things you enjoy the process of, regardless of whether you ever hit a specific goal
    • “I always say purpose is not your why, purpose is your ???????. It is the actions you take in the present and future that light you up.” – Jordan
  • Researchers studying older people found their actual sense of purpose was ??????? than expected… playing backgammon with friends, having coffee, that kind of thing, not “curing cancer”
  • Jordan’s own burnout as a doctor was a direct result of chasing big P purpose, trying to make up for his father’s death and save every patient, which was basically impossible

Burnout happens for 2 reasons when chasing big P purpose: most people never actually ???????, and even if they do, they spend 90-95% of their time doing things they didn’t ???????​

  • Even reaching the goal doesn’t fix it long term…
  • Jordan felt briefly good becoming a doctor, but the feeling ??????? and got replaced by anxiety about losing what he’d gained (classic loss aversion)

4 exercises for finding “purpose anchors”

  • The regret audit: imagine you’re on your deathbed with only days left, what would you regret never having the courage or time to do
  • The joys of childhood: think back to what lit you up before ???????​
  • The art of subtraction: write down everything you do at your job, cross out everything that ???????​
  • The spaghetti method: if nothing else works, just try ???????​

  • They take their losses with integrity, rather than tarnishing ??????​
  • “We rely on the prestige of our name… We are very, very jealous of our name.”

  • The better your relationship, the more likely you are to ??????​

  • Everything is handled between the two people who can directly make the decision

Merchant bankers sell ??????​

  • “People gladly pay a premium for lucidity of thought and economy of expression”

  • To think deeply ≠ to think in a complicated way
  • Theory and practice must always ??????​

Merchant bankers don’t read the newspaper or business publications

  • “I keep my ears open and people tell me everything that’s important”

​Show 71 – Mania for Subjugation | Dan Carlin’s Hardcore History​

Alexander is the best proof that you judge historical figures through the morality of your own era:

  • Philosopher king
  • Civilizing force
  • Historical arsonist who broke the log jam holding the world back
  • Great blender of civilizations and spreader of Hellenism
  • Butcher

Alexander benefited from nepotism, and being the son of a king in a monarchy is the best kind there is

Macedonian royal society read like a mafia crime family crossed with a daytime soap opera, with more homosexuality and sorcery than most crime families manage

  • The historians' adjective list: assassinations, executions, civil wars, hostage taking, incest, drunken murders, adultery, witchcraft
  • Philip II's mother bore three sons, all three became kings, all three died violently, two by assassination

The campaign record of Philip II, per historian Richard A. Gabriel: took the field every year of his 23-year reign except one when he was recovering from wounds, 28 campaigns, 11 sieges, 45 cities captured, seriously wounded at least five times

The army is arguably the most important part of the whole Alexander story, the tool that creates every opportunity for conquest

  • Philip made the Macedonian army, and conversely, the Macedonian army made Philip

Pike phalanx: Philip's invention, and the Cadillac style of warfare across the Mediterranean for the next 175 years

  • Hoplites: roughly 8 ranks deep with 7 to 9 foot spears
  • Pike phalanx: 16 ranks deep with 16 to 23 foot pikes, packed more closely together

The blended wine model of history: the further back you go, the more the ratio shifts from fact toward lore

  • Second World War is maybe 80% fact, 20% myth and misinformation
  • Alexander's era flips to something like 60% lore, 40% fact

What destroys Philip isn't an enemy general or a failed economy, it's his personal life and who he sleeps with

​Dr. Max Krummel: How Your Immune System Works & How to Improve It | Huberman Lab​

2 things actually matter for the aging immune system

  • Cells generally become less functional, including immune cells, and the body produces fewer new ones over time
  • DNA mutations pile up, which most people don’t realize
    • Skin cells rack up ten to thirty thousand mutations per cell per day from sun exposure alone
    • “your DNA… is susceptible to UV radiation, that’s one of the reasons we put on sunscreen”
    • Over years the body turns into a mosaic where no two cells are identical anymore, like Moroccan tile work
    • When you scratch yourself, the fittest mutant clone fills the gap, not necessarily the original version of you

Two reasons cancer rises with age

  • More years to accumulate cancer causing mutations
  • Immune system has seen so much weirdness by then that new weirdness doesn’t stand out anymore

Why does bad sleep make you more likely to get sick?

  • At night immune cells clear back into bone marrow while neutrophils come out into tissue and deposit collagen, a repair process
  • “this might be one of these areas where about ten factions of people know it but they don’t agree”, though the bone marrow clearing data specifically is pretty solid
  • 2 physical signs make the sleep and lymph connection obvious
