David Senra

David Senra says James Garfield almost certainly would have survived if doctors had left the bullet alone. Lodged in the fatty tissue below and behind his pancreas, the bullet was no continuing danger. Nature formed a capsule of thick, strong, fibrous tissue around it, walled it off from the rest of the body, and rendered it entirely harmless.

Shot 15 years later, the bullet in his back would have been found quickly by x-ray images and the wound treated with antiseptic surgery. He might have been back on his feet within weeks. With modern medical care he likely would have spent no more than a few nights in the hospital. The doctors instead rejected Lister's ideas. They kept probing the woun

David Senra says doctors rejected Joseph Lister's antiseptics even though the death rate among his surgical patients immediately plummeted. Lister knew the difference between his method and the old method was the difference between life and death. Alexander Graham Bell's telephone caught fire in an instant of understanding, and Lister's discovery, one of the most important advances in medical history, was dismissed.

The British surgeon struggled to convince the most experienced and admired physicians and surgeons in the United States of the critical importance of antisepsis, preventing infection by destroying germs. Almost none of them seriously considered putting the theory into practice.

David Senra says James Garfield hated being president because office seekers filled his days, while the work he wanted was to sit in the Library of Congress and read. Senra thinks Garfield spent 17 years in Congress before the presidency.

The office was one he did not seek and did not want. He never rose to the bait and was incapable of carrying a grudge, a trait neither Conkling nor Blaine understood. He called himself a poor hater, but he was a very good fighter and had never walked away from a fight. He wrote that he detested war, yet if it was brought to his door, the bringer would find him at home. The librarian of the Library of Congress, who knew him well, ranked him among the most d

David Senra says James Garfield would fight almost any cause except his own political future. He refused to seek an appointment or promotion of any kind, an early habit that became a central law of his life. He admitted he was morbidly sensitive about any reference to his own achievements, and he did not want to become president.

Becoming president against his will cost him his life 199 days after he was inaugurated. When the presidency came up, he looked the other way. He had spent 17 years in Congress and watched men whose desperate desire for the White House ruin their careers, their character, and their lives. He wrote that he had so long and so often seen the evil effects of the presid

David Senra says James Garfield paid for school by working as a janitor after he could not afford tuition. He convinced the school to trade labor for his education, and he changed from a rough canal man into a passionate, determined student.

He swept floors, hauled wood, and made fires, and he never tried to hide his poverty from the other students. Each morning he left the first lecture early, walked to the tower, and rang the school's enormous bell. He wrote that his tread was firm and free. He soon realized he was an extraordinary, talented student, and the more he learned, the more ambitious he became. In his diary he wrote that the ice was broken, that he was resolved to make a mark in

David Senra says James Garfield refused to praise poverty because he refused to romanticize his childhood. His extraordinary rise from fatherlessness and abject poverty made him the embodiment of the American dream, and he was raised in desperate circumstances.

James Garfield's father died just a few months after his 33rd birthday, in a log cabin he had built four years earlier. The cabin had one room, three small windows, and a rough wooden plank floor. Gaps between the logs were filled with clay in a futile attempt to shut out the brutal Ohio winters. His father's death left his mother with four children to feed and debts she could not hope to pay. James Garfield, the youngest, was not ye

David Senra says John D. Rockefeller bought the strongest refiners first because taking the top few in a new territory made everyone else fall in line. He started with the most powerful and most advanced plants, the best competitors. The executives had each been the leading operator in an important region and were not used to taking orders. They still accepted his view that consolidation was the way through, that Standard Oil would be the only company left, and that he would lead it.

One target's son recalled that his father examined Standard Oil's books, was astonished at the profits, and agreed to sell for stock. The first round of deals had to stay secret. Bought companies kept their man

David Senra says Andrew Carnegie's steel lost less than rival mills when prices had to fall, because the works with the newest equipment could cut prices and still run full. Carnegie insisted on the newest technology every time. Older competitors often did not see why the spending mattered. Buying the Frick Coke Company gave Carnegie Steel a dominant position in coke, and Lake Superior ore reserves gave a near-overwhelming advantage in high-quality ore. He wanted control of both raw materials.

The edge, Senra says, was mostly Carnegie: pressure to cut costs, a habit of taking any order that kept the plants full, and plowing earnings back into bigger plants and later equipment. For 25 years

David Senra says Jay Gould started with 50 cents. At 13, his father registered him at a high school in a neighboring town and left him there with a pile of clothes and 50 cents. J. P. Morgan, by contrast, was born into a rich family and inherited a merchant bank. Senra says no other robber baron came from a start like Gould's, and the weapon Gould used to build his wealth was an understanding of financial markets. Railroads became the center of his work early, and Senra says Gould, more than anyone else, created the national railroad map that is still in place.

Gould was barely five feet tall, smaller than Andrew Carnegie, and ambition made up for the lack of size. He was a financial engine

David Senra, reading Charles R. Morris's The Tycoons, says John D. Rockefeller got the oil refinery by pushing the Clark partners into a breakup and then outbidding them. As the friction grew, the Clarks kept threatening to dissolve the partnership. Rockefeller asked whether they meant it. They said yes. The next day they read a dissolution notice in the local newspaper, and their partner Andrews had sided with Rockefeller. At the auction, the 25-year-old Rockefeller outbid them. The bidding hit $72,000. A partner said the price was too high and handed the refinery over. The next year the refinery had sales of $1.2 million, in the 1860s.

Senra says Rockefeller often paid a fair price, and o

David Senra says Andrew Carnegie burned stalled railroad cars to clear the tracks. Shortly after Carnegie became superintendent of the Western Division, he shocked the other executives by doing it. The core job of the railroad was to keep traffic moving, and a stalled car was a bottleneck. He did the same thing over and over. He was not worried about the other executives' opinions. If he decided an action was right, he took it. Senra describes the habit as picking the objective, then cutting through conventions, competitors, or ordinary people in the way.

The rise had been fast. Tom Scott, one of the leading railroad executives of the period, mentored Carnegie, and the two shared an office

David Senra, reading Charles R. Morris's The Tycoons, says Andrew Carnegie was turning 30 when Abraham Lincoln died and was already wealthy, though he had been a factory bobbin boy hardly a decade and a half earlier and had not yet settled on a career. John D. Rockefeller was only 26, and his Cleveland oil refinery was one of the largest and most profitable in the country. Senra says Rockefeller may already have formed a plan to take over the whole industry. Jay Gould was 29 and was trying his hand as a railroad turnaround specialist. J. P. Morgan was 28, quietly learning the trade inside his father's banking network.

The four were never friends. Carnegie, Rockefeller, and Gould stood for t

David Senra, reading the preface of Charles R. Morris's The Tycoons, says Andrew Carnegie, John D. Rockefeller, and Jay Gould chased speed and experiments, while J. P. Morgan tried to rein in the competition the other three kept starting. Most businessmen around them wanted orderly markets and gentlemanly profits. Carnegie, Rockefeller, and Gould came to break that pattern. Morgan was the regulator.

Carnegie's plants were the biggest and the most automated, and his mantra was to cut costs, take share, and gain scale, with profits left to follow. Gould attacked in railroads and the telegraph and pushed public markets further than the people before him. Rockefeller took over world oil markets

David Senra says John D. Rockefeller beat other oil refiners by shaving costs across the whole company until small savings piled into an advantage no rival could catch. Standard Oil was the only company set up to balance refinery output, transportation, and distribution and to squeeze a little more at every stage. Rockefeller expected to stay in the oil business for the rest of his life, so the edge would compound decade after decade.

Competing refineries used Standard's distribution and added to its cash. Rockefeller bought a fleet of wide gauge tank cars from the cash-strapped Erie Railroad. Standard got first use of the cars, paid a lower freight rate, and collected rent when the railroa

David Senra, reading Charles R. Morris's The Tycoons, says Jay Gould made a fortune from Cornelius Vanderbilt's shipping losses after Vanderbilt cut cattle-shipping rates to a penny a head. Gould had already cornered the cattle market, so the steers filling Vanderbilt's trains were Gould's.

Gould and Vanderbilt each controlled a railroad and were fighting over the Erie. To steal traffic, an owner cuts prices. Some rivals might cut rates by 10% or 50%. In an Erie and New York Central cattle-shipping war, Vanderbilt slashed the rate to a penny a head and laughed as the trains filled with steers. The cheap haul turned Vanderbilt's losses into Gould's profit.

Plenty of people watered railroad

He calls the routine his drug: about 40 minutes of stretching, dynamic warmups, sauna, and red light therapy, roughly a two-hour start, then one cup of coffee. He doesn't drink or smoke pot, and that is what makes him feel good enough to be his best.

He still takes calls at five o'clock, works out, records another podcast, and heads to Montecito. The last three weeks have been incredible. If the work were not personally meaningful and enjoyable, he would not do it, even though it is hard at times.

You smoke 5MEO, go offline for ten minutes, and trip for about thirty. You see how small you are and call legacy bullshit, but not so you quit. You still want to be here, be happy, do your best, enjoy life while working really hard, and have a purpose.

Yes, completely. It came from an immigrant father and a first-generation family where education was everything, while he could not read and was not great at it.

Elon was talking about AI in 2007 and said the only thing in the entertainment business that can't be disintermediated by AI is live. Sports and live would stay important, and that is what gave him the idea behind Mari.

They were not idiots burning $44 million on buyouts. That money bought a hundred-year-old agency with a huge roster. He says they stole it, and it was the greatest deal he and Patrick ever did, not even close.

Disruption and dissent inside the other firm made Patrick and his partner the conquerors. Once that opened, the deal moved in about six months. Egon's arrival then let them incentivize everybody and take control of the company.

Dana rejects eight episodes and will not do the deal unless there are ten, even after being told there is nobody else. With no move left, the seller goes crazy on Kevin: ten episodes are needed to break stars, put some behind the paywall so people buy it, and keep the sport on ESPN. Bob Iger later tells Jimmy Patara to just give him the ten and figure it out on the schedule.

When Kevin Mayer called wanting the deal and the first offer was bad, Mark and his partner spent a weekend writing a letter on what they thought it was worth and why. The buyer came up, but not to their number, so they kept negotiating while pitching Bob Backish at Viacom to reinvent Spike as a sports channel.

Egon flew down, asked to buy a piece of the company, and said he wanted to go after IMG. The raise had been aimed at about $2 billion, with approaches to Martin Sorrell at WPP, and the answer was that a P firm had no chance. Egon asked for the numbers and three weeks, came back with an offer, and they went after IMG.

The founders podcast by David Senra is still way too unknown. Every week he reads an autobiography of an entrepreneur and connects how founders were similar or different. The best way he describes it is church, but for entrepreneurs.

David Senra, reading Jeremy Stern's profile Mark, says Mark Zuckerberg wants to escape Apple because he does not hold the ground his empire is built on. Inside his own court he is sovereign. Shareholders and the board cannot control him. He held the territory only once, when Facebook was a desktop site on the open web. When the smartphone appeared, he lost that ground and never got it back.

The loss has stayed with him. During the 2012 IPO he scrambled to rebuild Facebook and its advertising business around a mobile shift he had not seen coming. Senra reads that Facebook's move to mobile more or less made Apple's App Store, and the App Store in turn made Facebook. Zuckerberg does not like b

David Senra, reading Jeremy Stern's profile Mark, says Mark Zuckerberg cannot be removed from Meta. Zuckerberg holds majority control of Meta's voting power, and that control makes his removal effectively impossible. The same fact follows him into meetings with heads of state. Those officials will one day leave office and die. Zuckerberg could still be ruler of his empire in 50 years.

The profile puts that empire at 3.6 billion users and a market cap of $1.6 trillion. Senra says that is not a normal situation for a person to be in, and Zuckerberg has been in it since he was 19. Three hundred thousand years of evolutionary biology, the profile says, do not hand someone in that seat an easy w

David Senra, reading Jeremy Stern's profile Mark, calls the most important line in the profile the one that says you cannot take building away from Mark Zuckerberg, because he would not be himself if he stopped. He loves being at Meta because he still gets to create things. He did not set out to build a company. He just loves building things, and building is who he is.

The woman who has known Mark for 23 years asked him, around year 18 or 19, whether they were tired and could be done. She was tired. He was tired. They had gotten through a hard chapter, and she wanted other chapters in their life. Mark refused.

Their daughter later showed the same pull, untaught, delighted by bringing somet

David Senra, reading Jeremy Stern's profile Mark, says Mark Zuckerberg is pronounced dead every few years even while his empire survives and keeps expanding. The same cycle covers the last 10 to 14 years of the company Zuckerberg created.

After the IPO in 2012, a mobile crisis left Facebook declared an overvalued website whose audience had moved to a platform it could not monetize. Zuckerberg was considered in over his hoodie and too immature to run a public company. Between 2013 and 2017, teens left in a mass exodus for Tumblr and then Snapchat, and Facebook was left to die as the next MySpace after Snapchat rejected a $3 billion acquisition offer.

The arc matches the biographies Senra re

David Senra, reading Jeremy Stern's profile Mark, says nearly all of Facebook's management team quit in 2006 after Mark Zuckerberg, then only 22, rejected their pleas to sell the company to Yahoo for a billion dollars. The refusal set a central tenet of the culture: in the face of opposition, Zuckerberg is right.

Much of the inner circle has been with him for over 15 years, since before Facebook's IPO in 2012, and some were already there in 2006. Others long ago accepted that they cannot do what he does and that, despite many mistakes, he is in a class by himself. Many of the men and women have lives they never dreamed of, and they owe all of it to him.

They may simply be too grateful, a w

David Senra, reading Jeremy Stern's profile Mark, says Mark Zuckerberg has thought like an emperor since he was a child. At 12 he built a game set in the Roman Empire where the player conquered the world one territory at a time. In high school he excelled at Latin. Nearly a decade later he still recalled Jupiter's Latin verse: "I set no bounds in space or time. I have given empire without end."

At Harvard, one of the first websites he built was a class study tool for the art history course Rome of Augustus. In Facebook meetings held to fend off threats from Google, he ended speeches by declaring Carthage must be destroyed. All-hands meetings ended with him shouting domination. Sean Parker,

David Senra, reading from Vance Trimble's biography of Sam Walton, says Walmart got ahead of Kmart because Kmart ignored Walton's small-town stores and gave him a 10-year period to learn the discount business.

Sam Walton copied what he found in other stores. He studied Harry Cunningham, who came up with the Kmart concept, and said he took pieces of it and made Walmart as much like Kmart as he could. At the start Walmart was amateurish and far behind. Kmart let those stores stay out in little towns while Walton developed and learned. Walton said a competing store in a small town would have been unthinkable, and the small-town market protected him.

Kmart focused on major cities. Walton kept

David Senra says each of Sam Walton's four children has owned one-fifth of their parents' stock and property since 1954, and at the time of the recording the shares were worth $130 billion, $127 billion, or $117 billion depending on the child. Senra is not sure he remembers that opening figure and puts it at something like $5,000. One son later put the shares at no more than $5,000 each, because the parents had only a variety store or two.

Sam Walton and his wife created the trust when one son was 10 and a daughter was only 5. Father-in-law L.S. Robson, a banker and a lawyer, urged the early estate planning after he had already given Sam Walton's wife and her siblings equal shares in a vast

David Senra says Sam Walton started Sam's Wholesale Clubs by copying a membership wholesale club that Sol Price had already made successful.

On a sunny January morning in 1983, Sam Walton flew into San Diego to investigate a membership wholesale club. Sol Price, a California entrepreneur, had originated the idea five years earlier and was getting rich by selling merchandise at only 10% above manufacturing prices. Sam Walton figured he could do the same. He intended to borrow from Sol Price the way he had copied schemes from JCPenney, Herb Gibson, and other merchants. He returned to Bentonville, called his top strategists, and began a division of Sam's Wholesale Clubs.

Walton had spent year

David Senra says Sam Walton managed Walmart by walking stores, warehouses, and truck cabs, and some staffers called him that old slave driver, the boss people resigned or got fired under because the work was a pressure cooker. The public picture of a good old country boy in a soft velvet glove missed the iron fist inside. He can get a little tough if he sees things he does not like. He knew the business from top to bottom because he used to sweep the floor, keep the books, and buy the merchandise. A core asset was his willingness to try something new, and he repeated a low resistance to change, the RC factor, throughout the entire company.

On the road he flagged down one of his semi trucks,

David Senra, reading Charlie Munger's account, says Sam Walton beat bigger retailers by first knocking out small-town merchants with a more efficient system, and only then taking on the big chains.

Munger compared him to a prizefighter who wanted a record good enough for the finals, so he went out and fought 42 palookas. The result was knockout after knockout, 42 times. Walton might not have been able to tackle some titans head on at the time. With the better system he broke other small-town merchants, time after time. Then, as he got bigger, he started destroying the big boys.

The strategy was very shrewd. Scale and fanaticism combined to be very powerful.

David Senra, reading from Vance Trimble's biography of Sam Walton, says Sam Walton's golden rule at Walmart was that the customer is always right, and if the customer is not right, refer to rule number one.

Hardly a day passed without Sam Walton reminding an employee of that rule. Customer satisfaction was the first essential ingredient, and the rest of the approach was a combination of parts, basic and few. The standard was to go above and beyond when something came back.

A customer who bought a pair of shoes at Walmart and brought them back, for whatever reason, was to have the shoes cheerfully replaced. The sales clerk was also to throw in a pair of socks or stockings for the hassle of

David Senra says the second Walmart was such a mess that David Glass wrote Sam Walton off, even though Glass later became the CEO of Walmart 20 years on.

Sam Walton tried to recruit David Glass by taking him to the second Walmart ever opened. Glass thought Walton might have lost his marbles with discount-store foolishness and doubted the format had any future. Glass called it the worst retail store he had ever seen. Walton had bought a couple of trucks of watermelons, stacked them on the sidewalk, and put a donkey ride in the parking lot. It was 115 degrees. The watermelons began to pop, the donkeys began to do what donkeys do, and the mix ran all over the parking lot. Inside, the same mess

David Senra says Sam Walton's idea behind Walmart was absurdly simple: buy cheap, sell low every day, and do it with a smile. Making money was only a game, a test of his imagination and expertise to see how far he could drive a business concept. Wall Street had a hard time getting the drift of that.

The passage illustrates Charlie Munger's idea that you should find a simple idea and take it very seriously. Walton wanted to wake up every day, work on Walmart, and change his mind when new information arrived, turning from going left to going right. He was a genius in business with an iron mind, unwilling to compromise carefully thought out principles, and still flexible. If a course did not w
