n 1945, a young man dropped out of Harvard Law without a degree. He had $20 in his pocket and a family to feed. He became Warren Buffett's only partner. Together they built a $700 billion empire. He never used a computer. Rarely took meetings. Read for 6 hours a day until he was 99. His name was Charlie Munger. The man Buffett called "the abominable no-man" — because he could destroy any bad idea in 30 seconds flat. He didn't have a strategy. He had a system for thinking that made bad decisions almost impossible. I turned Munger's mental models into 12 Claude prompts. Here are all 12: 🧵

Naval Ravikant: "The only true test of intelligence is if you get what you want out of life" "There are two parts to that. One is getting what you want, so you know how to get it. The second is wanting the right things, knowing what to want in the first place. I could want to be a 6'8" basketball player and I'm not going to get that. That's wanting something you can't get. But there's also wanting something that's a booby prize, prizes that are just not worth having, or that create their own problems." Naval explains how people end up in places they never meant to be: "If you're not careful, you can end up in a place in life not only that you don't want to be, but one you didn't even mean to get to. Usually people end up there because they're going on autopilot with societal expectations. Or out of guilt. Or out of mimetic desire, our desires are picked up from other people. Go to law school, go to med school, go to business school. Or it might be what your parents expect. Guilt is just society's voice speaking in your head so you'll be a good little monkey." He shares a problem most people have: "We run on these four-year cycles. You join a startup, you vest over four years. College is four years. High school is four years. You go to law school, that's a 5-year cycle. You become a lawyer, that's a 40-year cycle. These are very long cycles. But the amount of time we spend deciding what to do and who to do it with? Very short. We spend one month deciding on a job where we're going to be for 10 years." Naval's rule: "If you're making a four-year decision, spend a year thinking it through. Really thinking it through. 25% of the time." He explains the Secretary Theorem: "It turns out the optimal time to search is about a third. By a third of the way through, you've seen enough to know what the bar is. Then anybody who meets or exceeds that bar is good enough. But here's the key: it's not time-based. It's iteration-based. You need to take opportunities quickly and bail out quickly. If you look at failed relationships, the biggest regret is usually staying after you knew it was over." Naval reframes the 10,000 hour rule: "Malcolm Gladwell popularized 10,000 hours to mastery. I'd say it's actually 10,000 iterations to mastery. Iteration is not repetition. Repetition is doing the same thing over and over. Iteration is modifying it with learning and doing another version. That's error correction. If you get 10,000 error corrections in anything, you will be an expert." On pessimism vs. optimism: "You want to be skeptical about specific things, every specific opportunity is probably a fail. But you want to be optimistic in the general. Something in here is going to work out. If something fails, it was a learning experience. It was an iteration. As long as you learned something, it's a win. You don't want to jump into the first thing. But once you find the match, you have to be willing to go all in. Move your chips to the center of the table." He concludes: "Most people are stuck in this gray bit. 'I'm half in, but I don't really know.' That doesn't work. It's a barbell strategy, black or white. Explore quickly, cut losses fast. Then when you find the right thing, compound into it."

Robert Mueller died last night. He was 81 years old. He had a wife who loved him for sixty years. He had two daughters, one of whom he met for the first time in Hawaii, in 1969, on a few hours of military leave, before he got back on the plane and returned to Vietnam. He had grandchildren. He had a faith he practiced quietly, without performance. He had, in the way of men who have seen real things and survived them, a quality that is increasingly rare and increasingly mocked in the country he spent his life serving. He had integrity. And tonight the President of the United States said good! I have been sitting with that word for hours now. Good. One syllable. The thing you say when the coffee is hot or the traffic is moving. The thing a man who has never had to bury anyone, never had to sit in the specific silence of a room where someone is newly absent, reaches for when he wants the world to know he is satisfied. Good. The daughters are crying and the wife is alone in the house and good. I want to speak directly to the Americans reading this. Not the political Americans. Just the human ones. The ones who have lost a father. The ones who know what it is to be in that first hour, when you keep forgetting and then remembering again, when ordinary objects become unbearable, when the world outside the window seems obscene in its indifference. I want to ask you, simply, to hold that feeling for a moment, and then to understand that the man you elected looked at it and typed a single word. Good. This is not a country having a bad day. I need you to understand that. Countries have bad days. Elections go wrong. Leaders disappoint. Institutions bend. But there is a different thing, a rarer and more terrible thing, that happens when the moral center of a place simply gives way. Not dramatically. Not with a single catastrophic event. But quietly, in increments, until one evening a president celebrates the death of an old man whose family is still warm with grief, and enough people find it acceptable that it becomes the weather. Just the weather. That is what is happening. That is what has happened. The world knows. From Tokyo to Oslo, from London to Buenos Aires, people are not angry at America tonight. Anger would mean there was still something to fight for, some remaining faith to be betrayed. What I see, in the reactions from everywhere that is not here, is something older and sadder than anger. It is the look people get when they have waited a long time for someone they love to find their way back, and have finally understood that they are not coming. America is being grieved. Past tense, almost. The idea of it. The thing it represented to people who had nothing else to believe in, who came here with everything they owned in a single bag because they had heard, somehow, across an ocean, that this was the place where decency was written into the walls. That idea is not resting. It is not suspended. It is being buried, in real time, with 7,450 likes before dinner. And the church said nothing. Seventy million people have decided that this man, this specific man who has cheated everyone he has ever made a promise to, who has mocked the disabled and the dead and the grieving, who celebrated tonight while a family wept, is an instrument of God. The pastors who made that bargain did not just trade away their credibility. They traded away the thing that made them worth listening to in the first place. The cross they carry now is a costume. The faith they preach is a loyalty oath with scripture attached. When the history of American Christianity is written, this will be the chapter they skip at seminary. Now I want to talk about the men who stand next to him. Because this is the part that actually breaks my heart. JD Vance is not a bad man. I have to say that, because it is true, and because the truth matters even now, especially now. Marco Rubio is not a bad man. Lindsey Graham is not a bad man. They are idiots, but not bad, as in BAD! These are men with mothers who raised them and children who love them and friends who remember who they were before all of this. They are not monsters. Monsters are simple. Monsters do not cost you anything emotionally because there is nothing in them to mourn. These men are something more painful than monsters. They are men who knew better, and know better still, and will get up tomorrow and do it again. Every small compromise they made had a reason. Every moment they looked the other way had a justification that sounded, at the time, almost reasonable. And now they have arrived here, at a place where a president celebrates the death of an old man and they will find a way, on television, to say nothing that means anything, and they will go home to houses where children who carry their name are waiting, and they will say goodnight, and they will say nothing. Their oldest friends are watching. The ones who knew Rubio when he still believed in something. Who knew Graham when he said, out loud, on the record, that this exact man would destroy the Republican Party and deserve it. Who sat next to Vance and thought here is someone worth knowing. Those friends are not angry tonight. They moved through anger a long time ago. What they feel now is the quiet, irrecoverable sadness of watching someone disappear while still being present. Of watching a person they loved choose, again and again, to become less. That is what cowardice costs. Not the coward. The people who loved him. And in the comments tonight, the followers celebrate. People who ten years ago brought casseroles to grieving neighbours. Who stood in the rain at gravesides and meant the words they said. Who told their children that we do not speak ill of the dead because the dead were someone's beloved. Those people are tonight typing gleeful things about a man whose daughters are not yet done crying. And they feel clean doing it. Righteous. Because somewhere along the way the thing they were given in exchange for their decency was the feeling of belonging to something, and that feeling is very hard to give up even when you can no longer remember what you gave for it. When Trump is gone, they will still be here. Standing in the silence where the noise used to be. Without the permission the crowd gave them. Without the pastor who told them their cruelty was holy. They will be alone with what they said and what they cheered and what they chose to become, and there will be no one left to tell them it was righteous. That morning is coming. Robert Mueller flew across the Pacific on military leave to hold his newborn daughter for a few hours before returning to the war. He came home. He buried his dead with honour. He served presidents of both parties because he understood that the institution was larger than any one man. He told his grandchildren that a lie is the worst thing a person can do, that a reputation once lost cannot be recovered, and he lived that, every day, in the quiet and unglamorous way of people who actually believe what they say. He was the kind of American the world used to point to when it needed to believe the story was true. He died last night. His wife is alone in their house in Georgetown. His daughters are learning what the world is without him in it. And somewhere in the particular hush that falls over a family in the first hours of loss, the most powerful man and the biggest loser on earth sent a message to say he was glad. The world that loved what America was supposed to be is grieving tonight. Not for Robert Mueller only. For the country that produced him and then became this. For the distance between what was promised and what was delivered. For the suspicion, growing quieter and more certain with each passing month, that the America people believed in was always partly a story, and the story is over now, and there is nothing yet to replace it. That is all it needed to be. A man died. His family is broken open with grief. That is all it needed to be. Instead the President said good. And the country that once stood for something looked away 🇺🇸 Gandalv / @Microinteracti1

The official listing ceremony of Pfuma REIT on @VFEX_ZW . Proud of this one. Oversubscribed on the capital raise and up more than 50% since listing about a month ago. This further confirms my current belief that if you have a good asset this is good time to come to the market

In 10 years, there will be two classes of people. Economists call it the "K-shaped economy" - and the next 2-3 years will decide which line you're on. I wrote a full breakdown below - the data behind the divide, and a practical framework you can start applying today.

@HyattRegencyHRE We had drinks at your bar. Your gins taste watered down. Tried to give feedback to your manager Alpa. His response was not five star. Everyone who asks me will hear this story. There is a lot a stake with this Hyatt project. Alpa is not a good ambassador . Disappointed!

“Fikile Mbalula is going to be president of the ANC if there is no serious intervention made to stop him, I warned you about this that this @MbalulaFikile if they allow him to do what he's doing he's going to lead them” EFF President Julius Malema “if it was a Marathon Mbalula is ahead Paul Mashatile is trying to catch up, I don't know how he will get there” @Julius_S_Malema

Wherever your thoughts may sway @GGuvamatanga has been a consequential Permanent Secretary in GoZ since 1980. This speaks volume of the man. He will join us tomorrow for @fridaydrinks_ in our No Holds Barred conversation. We thank him heartily for sharing a drink with us as we discuss the 2026 budget proposals presented to Parliament. Do you want to guess what Madyira will be drinking?

There’s a guy from Turkey named alpa who runs the bars at the Hyatt in Harare. Not open to feedback at all. I think they water down their drinks at the bars. He pretends he doesn’t know it. I suggest you randomly Amy white spirit from the pool bar then give him feedback. Delight

Innscor’s Growth: Money Never Sleeps If there is one superpower that Innscor has had, it is exceptional capital allocation. Capital allocation is the distribution, re-distribution, and investment of financial resources to maximise stakeholder profit. In short, it's about identifying opportunities and knowing how to organise, structure and deploy your capital to make the most of those opportunities. This is one of the most challenging tasks for executive teams to accomplish effectively, and it often determines whether they succeed or fail. One of the reasons OK Zimbabwe ended up in distress was due to issues with capital allocation, which we flagged back in 2023. Innscor, on the other hand, has consistently made sound allocation decisions. Whether through mergers and acquisitions (M&A), joint ventures, demergers, or new businesses, Innscor continually finds opportunities to drive growth and maximise returns. Innscor’s money never sleeps. Below is a visual showing the evolution of the group that clearly showns just how active the company is.
