17 of the most useful razors (rules of thumb that simplify decisions): 1. Bezos' Razors: • If unsure what action to take, let your 80-year-old self make it. • If unsure who to work with, pick the person that has the best chances of breaking you out of a 3rd world prison. 2. Skinner's Law: If procrastinating on an item, you only have 2 options: (a) Make the pain of not doing it greater than the pain of doing it. (b) Make the pleasure of doing it greater than the pleasure of not doing it. 3. Luck Razor: • If stuck with 2 equal options, pick the one that feels like it will produce the most luck later down the line. 4. Bragging Razor: • If someone brags about their success or happiness, assume it’s half what they claim. • If someone downplays their success or happiness, assume it’s double what they claim. 5. Hofstadter’s Law: • It always takes longer than you expect, even when you take into account Hofstadter’s Law. Every project costs 2x as much and takes 3x as long - even when you factor this into your projections. 6. Elon's Law: • If you have a project, combat Hofstader's Law by setting a ridiculously ambitious deadline. Even if it takes 3x longer than the deadline, you're ahead of everyone else. Elon Musk missing his super human deadlines is a feature rather than a bug. 7. Naval's Razors: • If you have 2 choices to make and it's 50/50, take the path that’s more painful in the short term. • If a task is worth less than your ambitious hourly rate - outsource it, automate it or delete it. 8. Munger's Law: • Never allow yourself to have an opinion on a subject unless you can state the opposing argument better than the opposition can. Steelman Arguments > Strawman Arguments 9. Hitchen's Razor: • What can be asserted without evidence can be dismissed without evidence. 10. Newton's Flaming Laser Sword: • If something can be settled by experiment or observation, then it is not worthy of debate. UFC 1 >>> Decade long debates on the best martial arts 11. Joe Rogan's Razors: • If unsure what action to take - ask what the hero in the movie would do. • If you're intensely passionate about something and nobody around you is interested in it - assume the scale of the internet might help you find them. 12. Taleb's Surgeon: • If presented with two seemingly equal candidates for a role, pick the one with the least amount of charisma. The uncharismatic one has got there despite their lack of charisma. The charismatic one has got there with the aid of their charisma. 13. Discomfort Razor: • The more uncomfortable the activity, the more likely it will lead to growth. • The more comfortable the activity, the more likely it will lead to stagnation. 1000 uncomfortable hours > 10,000 comfortable hours 14. Checkhov's Gun: • When telling a story, if it's non-essential - don't include it. "If you say in the 1st chapter that there is a rifle hanging on the wall, in the 2nd or 3rd chapter it absolutely must go off. If it's not going to be fired, it shouldn't be hanging there." 15. Occam's Razor: • Simple assumptions are more likely to be correct than complex assumptions. Avoid Occam's Duct Tape: • Someone who approaches a problem with a ridiculously large number of assumptions. 16. Walt Disney's Rule: • If struggling to think clearly about a subject, draw it out. See picture. 17. Schwarzeneggers' Rule: • Never need to monetize your artistic pursuits. You won't have to sacrifice your inner joy and vision for a payday. Arnold made millions from property and D2C bodybuilding guides so he never had to say yes to acting gigs he didn't like. Collected by George Mack (https://twitter.com/george__mack) Pircture: Walt Disney's drawing he made in 1957 of the Media Empire he wanted to build. It's iconic.

Seems that there are more laws from Charlie Munger: MUNGERS LAW #1 - IF IN DOUBT, INVERT. “It is remarkable how much long-term advantage people like us have gotten by trying to be consistently not stupid, instead of trying to be very intelligent.” Avoiding stupidity is easier than seeking excellence, yet nobody does it. His golden piece of advice is two-fold: 1. Avoid being lazy 2. Avoid being unreliable No matter how connected, well-read or talented you are - if you don't avoid these two, you are destined to fail. A young man once asked Charlie - "What advice do you have for someone like me to succeed in life?" Most gurus would respond with "Follow your passion" or "Find your why" Munger quipped back: "Don't do cocaine. Don't race trains to the track. And avoid all AIDS situations." Inversion is useful for wooly problems like happiness. Instead of asking "How do I become happy?" Ask, "How do I become depressed?" 1. Poor sleep 2. Shit diet 3. Meaningless work 4. No exercise 5. Boring friends Avoid those 5 and you've figured out 95% of happiness. MUNGERS LAW #2 - UNDERSTAND INCENTIVES “It’s much easier to decode life when you view events as an emerging property of underlying systems” - @danielgross And all human systems can be explained by ONE THING - Incentives. FedEx tried every management technique to get their workers to move all packages into one central location each night. It was "Impossible". One day they decided to pay workers by the SHIFT instead of by the HOUR. Miraculously, they never had the problem again. "Show me the incentives and I will show you the outcome" - Munger "If you have a dumb incentive system, you get a dumb outcome" - Munger MUNGERS LAW #3 - BE VERY CAREFUL WITH YOUR IDENTITY What you shout out to other people, you pound into your own psyche. Your identity is a proxy between your consciousness and reality. Identity distorts your sense making apparatus. "Self-image is the prison. Other people are the guards." - @naval The biggest danger of mental models is that you begin to identify as a "smart person who understands cognitive biases" This is the ultimate trojan horse. You become too scared to make mistakes - the guy who has it all figured out can't make mistakes. If you can't make mistakes, you can't iterate. If you can't iterate, you can't win. Ironically, identifying publicly as an idiot frees you. (PS. I'm not smart - I'm a moron.) If decision making theory was the sole requirement to do great things, psychology professors would be running the world - not classrooms. I call this "The Instagram Paradox": The desire to identify how successful and happy you are to others is the thing that prevents you from being successful and happy. Irony. You can't present an image of you as an expert and co-exist in beginners mind at the same time. MUNGERS LAW #4 - KNOW THE OTHER SIDE BETTER THAN THEY KNOW IT Charlie never allows himself to have an opinion on a subject unless he can state the opposing argument better than the opposition can. Don't create STRAW MAN arguments, create STEEL MAN arguments. If you're a marxist, you should know the benefits of consumer capitalism better than Adam Smith. In every debate, be like @BretWeinstein moderating @SamHarrisOrg & @jordanbpeterson. State the strengths of your opposition and the weakness of your own. STEEL MANNING is Antifragile. You either prove your theory correct or end up with a better idea. Win-Win. STRAW MANNING is Fragile. You spend years emotionally attached to the first idea that got in your head. Lose-Lose. MUNGERS LAW #5 - YOU GET WHAT YOU DESERVE "The safest way to get what you want is to earn what you want" - Munger (How to find a romantic partner?) - "Be worthy of a worthy mate" - Munger Instead of having grandeur fantasies about how people will one day realize your genius, just focus on becoming that person. The ultimate cheat code to life is to realize that there are no cheat codes. MUNGERS LAW #6 - KNOW YOUR CIRCLES OF COMPETENCE “Knowing what you don’t know is more useful than being brilliant.” - Munger “Acknowledging what you don’t know is the dawning of wisdom.” - Munger Whenever I hear a novice speak arrogantly about an area of my expertise, I get a smug feeling that lasts for about 5 seconds. I then sink into panic and think about subjects I have confident opinions in yet no experience. The Dunning-Kruger effect can only be seen in others. Best till LAST... MUNGERS LAW #7 - AVOID SELF PITY "Whenever you think that some situation or some person is ruining your life, it’s actually you who are ruining your life. It’s such a simple idea. Feeling like a victim is a disastrous way to make go through life." - Munger Munger had a friend that carried a big stack of index cards. Whenever this friend heard someone feel sorry for themselves, he would sarcastically give them one that read: “Your story has touched my heart, never have I heard of anyone with as many misfortunes as you”. "I suggest that every time you find you’re drifting into self pity, I don’t care what the cause — your child could be dying of cancer — self-pity is not going to improve the situation. Just give yourself one of those cards." - Munger I always thought the "YOUR CHILD COULD BE DYING OF CANCER" line was a bit crass for a billionaire to advise people. Then I did a bit of research into Charlie's life... When Charlie was 29, his wife divorced him and he lost everything - including his home. Shortly after the divorce, he found out his 9 year old son Teddy had leukemia. Charlie spent his remaining pennies paying for his son's medical bills... He used to leave the appointments walking the streets crying. At the age of 30, Charlie Munger was: 1. Broke 2. Divorced 3. Burying his dead child He had every excuse to give into self pity. We live in a better place because he didn't. Later in his life, Charlie was told he was going to lose sight in his remaining eye. Charlie's NUMBER ONE hobby is reading. This news should've DESTROYED him. How did he respond? “It’s an opportunity for me to learn braille.” - Charlie told friends. The ultimate reframe. SUMMARY: 1. Avoid sloth and unreliability 2. Incentives are a superpower 3. Be careful with your identity 4. Steelman arguments 5. Be worthy of a worthy mate 6. Dunning-Kruger effect is easier to see in others 7. Where is the opportunity for you to learn Braille? https://www.linkedin.com/pulse/7-laws-life-charlie-munger-manifesto-trent-anderson-mba/

A few days ago I spoke to a friend I haven't seen for a few years. She wants to found a tech company and looks into different categories, like well-being, learning, and food. She wanted me to suggest which category has the biggest opportunity. Each category she looks in, she finds more questions than answers. Also, people from each category say that the category is hard. I said that, of course, it is hard to start and create something new in any category. It is hard because you always have more questions than answers initially, and you need to find those answers somehow. Many answers are possible to find only by trying and failing, not by researching or thinking. And failing is hard, yet necessary for success. There is no self-evident & clear new biggest opportunity in any category. Instead of looking for that, just pick the idea/concept, you believe the most and start doing it without knowing everything in advance. And first thing in doing is to find your first believers who will be your future partners. You can find them easier if you have committed yourself to a specific idea. In that case, speak to people and invite them to join your journey and see what will happen. Good luck with founding your new company! Photo: I made it in Italy a few weeks ago. P.S. This is my first insight posted from Qoorio web (not app).

I like this attitude: many answers can be found only by trying & failing. however it is not smth we learn at school. It's interesting how start-ups saw 2020- it was a good year, because they are used to challenges at an ongoing basis
