War is a violent and bloody business, but it's rarely a no-holds barred free-for-all. Instead, codes of conduct that determine what is and isn't honorable behavior on the battlefield have existed since ancient times.My guest today explored these various codes in a book she wrote during the decade she spent teaching at the United States Naval Academy. Her name is Shannon French, she's a professor of ethics and philosophy, and her book is The Code of the Warrior: Exploring Warrior Values Past and Present. Shannon and I begin our conversation with the pointed questions she used to pose to the cadets she taught as to how being a warrior was different than being a killer or murderer, and when killing is and isn't ethical. She then explains how the warrior codes which developed all around the world arose organically from warriors themselves for their own protection, and how these codes are more about identity than rules. Shannon and I then take a tour of warrior codes across time and culture, starting with the code in Homer's Iliad, and then moving into the strengths and weaknesses of the Stoic philosophy which undergirded the code of the Romans. From there we unpack the code of the medieval knights of Arthurian legend, what American Indians can teach soldiers about the need to make clear transitions between the homefront and the warfront, and how the Bushido code of the samurais sought to balance the influence of four different religions. We end our conversation with the role warrior codes play today in an age of increasingly technologized combat. Get the show notes at aom.is/warriorcode.

The topic of health and fitness has long been a popular one for magazines, and in most recent times, for blogs and Instagram accounts. But what these modern publishers and influencers probably don't realize is that they're standing on the shoulders of an ambitious eccentric who laid the foundation for much of modern American media: Bernarr Macfadden.My guest today is Mark Adams, who wrote a biography of this proto fitness guru called Mr. America: How Muscular Millionaire Bernarr Macfadden Transformed the Nation Through Sex, Salad, and the Ultimate Starvation Diet. Mark and I begin our conversation with how Macfadden discovered a passion for health and fitness as a young man and failed at his attempt to become a personal trainer, despite coining the motto "Weakness is a crime; don't be a criminal." We then discuss how Macfadden went on to start the highly successful magazine, Physical Culture, and then an entire publishing empire, which pioneered many of the confessional, first-person, personal branding techniques still used today. Mark shares the tenets of Macfadden's sometimes sound, sometimes wacky health philosophy, including his advocacy of fasting, and what happened when Mark tried out some of Macfadden's protocols on himself. Mark and I then delve into how Macfadden founded a utopian community in the New Jersey suburbs, was convicted of obscenity charges, trained fascist cadets for Mussolini, and ran for U.S. senator on a physical fitness platform. We end our conversation with why Macfadden was forgotten, and yet had a lasting effect on the world of health and fitness, as well as media as a whole. Get the show notes at aom.is/macfadden.

This is a re-broadcast. The episode originally ran in February 2019. Practicing minimalism with your possessions has been a trend for the past decade, and it can be a worthy practice, as long as you use it as a means to greater efficacy outside your personal domain, rather than just an end in itself. But there's arguably a minimalism practice that's even more effective in achieving that greater efficacy: digital minimalism. My guest has written the definitive guide to the philosophy and tactics behind digital minimalism. His name is Cal Newport and this is his third visit to the AoM Podcast. We’ve had him on the show previously to discuss his books So Good They Can’t Ignore You and Deep Work. Today, we discuss his latest book, Digital Minimalism: Choosing a Focused Life in a Noisy World. We begin our conversation discussing why digital tech feels so addicting, why Steve Jobs didn’t originally intend for the iPhone to become something we check all the time, and why the common tips for reducing your smartphone use don't work and you need to implement more nuclear solutions instead. We then discuss the surprising lesson the Amish can teach you about being intentional about technology, how cleaning up your digital life is like decluttering your house, and why he recommends a 30-day tech fast to evaluate what tech you want to let back into your life. Cal then makes an argument for why you should see social media like training wheels for navigating the web, how to take those wheels off, and why you should own your own domain address. We end our conversation exploring what you should do in the free time you open up once your digital distractions are tamed, and the advanced techniques you can use to take the practice of digital minimalism to the next level. I think you'll find this a tremendously interesting and important show. Get the show notes at aom.is/digitalminimalism.

When someone is struggling with a seemingly easy problem, someone else might say, "Come on, it's not rocket science!" The inference being that rocket science represents the pinnacle of complexity. But my guest today argues that the study of rocket science contains some simple, overarching principles that cannot only be universally understood, but universally applied to all kinds of problems and decisions. His name is Ozan Varol, he served on the operations team for the 2003 Mars Exploration Rovers project, and he's the author of the book Think Like a Rocket Scientist. We begin our conversation discussing why Ozan went from studying astrophysics to going to law school, and how his scientific background has influenced his legal career. We then dig into ways that the same thought processes that enable spacecraft to travel millions of miles can also be applied to moving forward in work and life. Ozan explains how scientists deal with uncertainty and why you have to constantly question the way things are done to get better results. We end our discussion by talking about how to use thought experiments to solve problems, how to test ideas, and how to actually learn from your failures.

Many dream of leaving the city and all its tethers and obligations and creating a simpler, more independent life farther from the mainstream population and entirely off the grid. But how do you go from that daydream to making such a move a reality? My guest walks us through the process today. His name is Gary Collins, he made the leap himself and now lives off the grid in Northeast Washington, and he's the author of several books on off grid living as well as simplifying your life. We begin our conversation today with why Gary decided to leave his conventional, urban, 9-5 existence to find a freer lifestyle, and how he defines being off the grid. We then get into why Gary thinks you should make the move to living off the grid in a series of steps, the first of which is to simplify your existing life in three main ways. Gary then makes the case for why living in a RV should be the next step in your journey, before discussing the process of finding land for your off grid home, and the factors to consider in picking a locale. From there we get into how those who live off the grid take care of water, sewage, power, and internet, how they construct the house itself, and what to know about the start-up costs involved. We end our conversation with a discussion of getting off the grid in a more metaphorical way by quitting social media, and why Gary thinks you should pull the plug on those platforms, even if you're an entrepreneur.

Everyone feels under greater psychic pressure these days, but we adults hope that children, who have always been seen as naturally resilient, have been spared the stress. Unfortunately, kids are increasingly experiencing mental health problems like anxiety at younger and younger ages, and this trend has been going on for years. My guest today wrote a cover article for The Atlantic on the causes and cures of this phenomenon. Her name is Kate Julian and we begin our conversation today by describing the extent to which problems like depression, anxiety, and even suicide have been on the rise among children, and how these issues correlate with continued problems later in life. We then talk about the possible causes behind the increase in childhood anxiety, and whether technology and social media are to blame. We then delve into the idea of how parents are perpetuating their children's anxiety through their own anxiety and their willingness to make accommodations to keep their kids calm and happy. We get into the idea that getting your children comfortable with being uncomfortable can inoculate them against anxiety, and end our conversation with a discussion of whether more exposure to the news of a tumultuous world might actually make kids more resilient.

We've all asked "what if" questions about our life: What if I had majored in art instead of business? What if I had let my best friend know I liked her as more than a friend? What if I had taken the job offer in Colorado? Sometimes contemplating the imagined possibilities of these alternative histories fills us with sharp pangs of regret. My guest today says that's not necessarily a bad thing. His name is Neal Roese and he's a professor of psychology and marketing and the author of If Only: How to Turn Regret Into Opportunity. Neal and I begin our conversation by unpacking how asking "what if" is to engage in something called "counterfactual thinking," and how you can create a downward counterfactual, in which you imagine how a decision could have turned out worse, or an upward counterfactual, where you imagine how a decision could have turned out better. Neal then explains why living without regret isn't actually that healthy, and why even though regret is an unpleasant feeling, it can be an important spur towards greater improvement, action, and agency. We then do get into the circumstances in which regret can become a negative force, before turning to what Neal's research says are the most common regrets people have in life. At the end of our conversation, we pivot to talking about how imagining how your life could have turned out worse, can make you feel happier. Get the show notes at aom.is/regret.

According to Silicon Valley, self-driving cars are the future of transportation. Instead of owning and driving a car, you can just summon an AI-operated vehicle with your smartphone and have this superpowered computer taxi you to your destination. No more car maintenance, no more traffic, no more accidents. It may sound great on the face of it, but my guest today argues that shifting from being a driver to being a mere passenger represents an existential risk in and of itself, as well as a symbol for the potential loss of much broader human values. His name is Matthew Crawford and he's a philosopher, mechanic, and hot rodder, as well as the author of Shop Class as Soulcraft. In his latest book, Why We Drive: Towards a Philosophy of the Open Road, Matthew investigates the driver’s seat as one of the few remaining domains of skill, exploration, play, and freedom. Matthew and I begin our conversation discussing how freely moving around in our environment is a big part of what makes us human and then explore how shifting from being the drivers of our own cars to the passengers of self-driving cars could result in a loss of that humanity by eliminating agency, privacy, and proficiency. As our wide-ranging conversational road trip continues, Matthew and I take detours into what things like hot rodding and demolition derbies can tell us about mastery, play, and competition. We end our conversation on what driving ultimately has to do with the overarching idea of self-governance. Get the show notes at aom.is/whywedrive.

We've all been there: you're sitting at home some evening and you don't have plans, you haven't heard from family or friends for awhile, and you've got things on your mind, but don't feel like there's anyone you can talk to about them. You feel down and adrift, and sense an almost physical ache in your heart. You're experiencing loneliness, and my guest today says we ought to interpret this feeling the way we would hunger or thirst -- as a signal that we have a need that we should take action to fulfill. His name is Dr. Vivek Murthy, he served as the 19th Surgeon General of the United States, and he's the author of the book Together: The Healing Power of Human Connection in a Sometimes Lonely World. We begin our conversation discussing what loneliness is exactly and how we can feel interpersonally fulfilled in some areas of our lives, and yet lonely in others. Vivek then walks us through the very tangible harm loneliness can do to our mental health, before exploring why loneliness has been increasing in the western world. Vivek and I then discuss how loneliness affects men in particular. We end our conversation with things we can all do to battle the loneliness epidemic and feel more connected to those around us.

Which branch of the military has the toughest training course for its officers and special operators is a matter of animated debate, but there's no question that the Army's Ranger School is a viable candidate for carrying that designation. Over nine weeks, and three grueling phases, soldiers undergo physical, mental, and emotional challenges that test their endurance, resilience, and leadership. My guest today went through Ranger School twice: first as an infantry officer in 2004, and then just last year as the first journalist to embed with a class all the way through the course. His name is Will Bardenwerper and he wrote an article about his experience for Outside Magazine called "Army Ranger School Is a Laboratory of Human Endurance." Will and I begin our conversation with why he wanted to observe Ranger School from a third-party perspective after participating in it firsthand as a soldier. Will then explains the difference between earning your tab by graduating from Ranger School and being an official Army Ranger who belongs to the Ranger Regiment special operations force. Will then gives us a big picture overview of the three phases of Ranger School: Benning Phase, Mountain Phase, and Swamp Phase. We then dive into what happens in each phase, taking side trips along the way into the controversy of allowing women into the course, whether or not it's gotten easier since Will went through, and the importance of doing well in the combat patrol exercises and peer reviews in which the students participate. We end our conversation discussing the lessons in endurance that civilians can take away from those who graduate from Ranger School and earn the tab. Get the show notes at aom.is/rangerschool.
