READ THIS BOOK - Poor Charlie's Almanack

Since early 2020 when COVID started, I’ve gone on quite an exploration. In 2020 alone, I read over 25 books, all of which were either sci-fi (like Dune, The Three Body Problem, Snow Crash) or non-fiction. For some reason - maybe because I was unemployed and taking care of a newborn - my mind needed to work out. I had no idea that I would go on such a bender of books, but my brain was just saying “read something, learn something.”

So I ordered a book I’ve wanted to read for quite some time: Poor Charlie’s Almanack, a compendium of speeches by one of the best minds and investors of the 20th century, Charlie Munger.


I’ve been interested in the stock market and investments since I was young. I started investing - and losing money and learning and repeating - when I was 18 years old. I wanted go at it alone and learn myself without the help of books and other investors. Then when I was 19, I interned at a small wealth management team, and I got to sit next to the Chief Investment Officer, a brilliant and humble mind who taught me not only how little I knew, but how little he knew and how much he always strived to learn.

My arrogance and rebelliousness as a twenty-year-old ignored his advice to understand how little I knew. I was going to conquer the world! Yeah. Right...

It wasn't until recently that I whole-heartedly acknowledged how little I know. Spend a moment and really think about this statement: you know close to nothing. Truly. Think about how much there is to know in the world. Think about the number of Wikipedia entries and the endless amounts of books. How many of these would you be able to competently explain to a 5 year old? .01%?

Don’t worry even the majority of the most brilliant people in the world basically know nothing in relative terms. Yeah, he/she is one of the greatest physics minds in the world, but they don’t know shit about anything else.

ANYWAYS, the point I’m making is it was very psychologically freeing to realize how little I knew (and even many things I thought I knew well, I realized I was full of shit). This made me more open to learn and understand other points of view. It’s a win!


Which brings me back to investing and Charlie Munger and Poor Charlie’s Alamanack. If there is one person to learn investing from, I’d bet it’s Charlie Munger. Why? Because of the way he thinks. Because of the way he approaches problems and solves them. Because of his long-term vision. Because many times investing is not even about a company’s finances/numbers, it’s about common sense.

There is no one else like Charlie Munger. He will not only teach you about investing, he will teach you to think. And that, my friends, is an area we can all improve.

Buy the book, rent it, whatever, but please read it! Below are all my notes and quotes from the book to give you a feel what really stood out to me. enjoy!

Notes & Quotes

Multiple Mental Models Approach to Business (estimated to be 100 of them - Click here for list)

  • His models supply the analytical structure that enables him to reduce the inherent chaos and confusion of a complex problem into a clarified set of fundamentals. 

    This stitches together the analytical tools, methods, and formulas from such traditional disciplines as history, psychology, mathematics, engineering, biology, physics, chemistry, statistics, economics, and so on.

  • “if you have just one or two [mental models] that you’re using, the nature of human psychology is such that you’ll torture reality so that it fits your models, or at least you’ll think it does.”

  • “Just as multiple factors shape almost every system, multiple models from a variety of disciplines, applied with fluency, are needed to understand that system.” 

    1. Mathematics / Statistics 

      1. Compound interest from mathematics

      2. “The Fermat/Pascal system is dramatically consonant with the way the world works.”

      3. “Decision tree theory”

    2. Engineering

      1. Redundancy / Backup system model

      2. Breakpoints

      3. Quality Control (like what Deming did in Japan)

    3. Finance / Accounting / Economics

      1. Advantages of Scale

    4. Physics / Chemistry / Biology

      1. Breakpoint / tipping-moment / autocatalysis models from physics and chemistry

      2. Modern Darwinian synthesis model from biology - work of late 1930s and 1940s of discoveries of geneticists and natural historians to determine how change of genes could account for evolution of biodiversity: The organism acts, and has evolved, to further the interests of its genes.

    5. Philosophy

    6. Psychology

      1. Cognitive misjudgment models from psychology (I.E. Charlie’s 25 models from Psychology of Human Misjudgment talk)

      2. First principles - Look at every business and try to determine what their main psychological aim is for their business.

        1. Munger talks about a case study in Coke and says “[Coke] is going into the business of creating and maintaining conditioned reflexes. The ‘Coca-Cola’ trade name and trade dress will act as the stimuli, and the purchase and ingestion of our beverage will be the desired response.

        2. “How does one create and maintain conditioned reflexes?...(1) by operant conditioning and (2) by classical conditioning, often called Pavlovian conditioning.”

          1. For operant conditioning - we need only (1) maximize rewards of our beverage’s ingestion and (2) minimize possibilities that desired reflexes created by us will be extinguished through operant conditioning by competing products.

          2. Persuasion

    7. Social Proof

    8. Milgram experiment - Used authority to manipulate high-grade people into doing things that were clearly and grossly wrong 

    9. Pavlovian association - if people tell you what you really dont want to hear - what’s unpleasant - there’s an almost automatic reaction of antipathy

    10. Consistency principle

    11. Operant conditioning 

    12. Incentive-caused bias - what is good for the professional is good for the client and the wider civilization

      1. Says Engineering QC is based on math of Pascal & Fermat and also based on what Deming brought to Japan with QC  

  • The Lollapalooza Effect - Forces / factors / models / biases operating in the same direction reinforce and greatly amplify each other in effect

    4. Pavlov

    5. Planck 

    6. Adam Smith

  • Peter Kaufman (Editor of Poor Charlie’s Almanack) - Speech on Multidisciplinary Approach to Thinking

    1. Why multidisciplinary thinking (“MDT”) is important

      1. Austrian philosopher Ludwig Wittgenstein said, “To understand is to know what to do.”

      2. St. Lous Cardinals great, Lou Brock, “Show me a man who is afraid of appearing foolish and I’ll show you a man who can be beat every time.”

    2. The Three Buckets - A statistician’s best friend is what? A large, relevant sample size. And why? Because a principle derived from a large relevant sample size can’t be wrong can it?

      1. Bucket 1 is 13.7 billion years. Is that a large sample? It’s the largest one in the whole universe. There is no larger sample. Because what is it? It’s the inorganic universe. Physics. Geology. Anything that’s not living goes in my bucket number 1. 13.7 billion years.

      2. Bucket number 2 is 3.5 billion years. It’s biology on the planet Earth. Is that a big sample size? Is it relevant? We’re biological creatures. Let me ask you this, inorganic, bucket number one, is it relevant? We live in it. So bucket number one we live in, 13.7 billion years. Bucket number two is what we’re part of, biology. 3.5 billion years. 

      3. Bucket 3 - 20,000 years of recorded human history. That’s the most relevant of all. That’s our story. That’s who we are.

    3. Models he discusses

      1. Mirrored reciprocation - based on Newton’s Third Law of Motion (for every action, there will always be an equal and opposite reaction) - Every interaction you have with another human being is merely mirrored reciprocation. Therefore, be a good person! 

        1. We test this concept by looking at the three buckets, and it confirms that Newton’s Third Law of Motion has been in effect for 13.7 billion years so same for 3.5 billion years, then he uses the example of grabbing a cat by its tail. It;s not going to like this and try to claw you senseless. Equal and opposite reaction.  

      2. Compound Interest

        1. Einstein said, “The most powerful force in the universe is compound interest.” Einstein also said it’s the greatest mathematical discovery of all time. He said it’s the eighth wonder of the world. 

        2. Kaufman defines as: dogged incremental progress over a very long time frame.

          1. You have to be constant, not intermittent.

      3. Win-Win is SO MUCH better than Win-Lose

        1. What happens you insert win-win in any game theory scenario, what do you get? Optimal every time.

        2. What must you necessarily do if you’re interested in achieving win-win frameworks with your important counterparties in life? You must understand the basic axiom of clinical psychologyThe basic axiom of clinical psychology reads, ‘If you could see the world the way I see it, you’d understand why I behave the way I do.’ 

          1. And I say if you buy the axiom, which you should, you must buy the two corollaries as well because they’re logical extensions. They’re undeniable.  

          2. Corollary number one, if that axiom is true and you want to understand the way someone’s behaving, you must see the world as they see it. 

          3. Corollary number two, if you want to change a human being’s behavior and you accept that axiom, you must necessarily, to get them to change, change how they see the world.

        3. Win-Win is the secret to leadership. The secret to leadership is to see through the eyes of all six important counterparty groups and make sure that everything you do is structured in such a way to be win-win with them. The six are: 

          1. Customers

          2. Suppliers

          3. Employees

          4. Owners

          5. Regulators

          6. Communities you operate in

          7. If you can truly see through the eyes of all six of these counterparty groups and understand their needs, their aspirations, their insecurities, their time horizons. How many blind spots do you have now? Zero. How many mistakes are you going to make? You’re going to make zero. People don’t think this is possible. It’s really easy. To understand is to know what to do. 

    4. Einstein’s Five Ascending Levels of Cognitive Prowess (from best to worse):

      1. Simple - Why is simple better than genius? Because you can understand it!

      2. Genius

      3. Brilliant

      4. Intelligent

      5. Smart
