人畜無害はノーリスク・リターンな徳である 15.09.2026 13минIs being harmless the same as being a good person? In this episode, I question why modern society often treats harmlessness as a moral virtue. Traditional virtues such as courage, justice, generosity, and honesty usually involve some kind of cost: risk, conflict, sacrifice, or responsibility. Harmlessness, however, can often be achieved simply by avoiding conflict, strong opinions, and difficult situations. There is nothing wrong with living quietly and peacefully, but not harming others is different from actively doing good. Perhaps we have begun giving too much moral credit to people simply because they appear pleasant, gentle, and unlikely to cause trouble. -
AIで空いた時間に、仕事をしてはいけない 14.09.2026 11минWhat should we do with the time AI saves us? In this episode, I argue that efficiency should not simply lead to more work. If a task that once took three hours now takes one, perhaps the remaining two hours should belong to us. We can play games, read, walk, nap, or do nothing at all. Modern life often turns even rest into another productivity tool, but rest does not need to justify itself. AI and automation should not exist merely to increase the density of work. Their real promise may be giving human beings more time in which they do not have to work. -
苦しみの資産化 ── なぜ不幸はYouTubeで価値を持つのか 13.09.2026 11минWhat happens when human suffering becomes an asset? In traditional accounting, humiliation, loneliness, unemployment, and painful memories have no monetary value. But on YouTube, those same experiences can generate views, donations, subscribers, and advertising revenue. In this episode, I explore the strange economics of turning personal suffering into content. The most disturbing possibility is that success may create a conflict: you want to escape your suffering, but your audience may value you precisely because you suffer. When unhappiness becomes profitable, recovery can reduce your market value. Perhaps some parts of life should simply remain outside the market. -
深いことを言いすぎる時代 12.09.2026 11минWhy does everyone sound so “deep” these days? In this episode, I explore the inflation of philosophical language online: words like freedom, meaning, identity, structure, desire, and authenticity now appear everywhere. The problem is not thinking deeply, but mistaking abstract language for depth itself. When profound-sounding words are used constantly, philosophy can become little more than background music. I argue that the weight of a thought may depend partly on how long someone has remained silent before saying it. Perhaps true depth comes not from speaking endlessly about life, but from knowing when not to. -
壁打ちは環境負荷が高い 11.09.2026 10минIs AI “brainstorming” bad for the environment? In this episode, I half-jokingly ask whether we really need data centers running around the world just to help us organize our thoughts. People now use AI to reflect on their careers, emotions, goals, values, and daily frustrations—tasks that once required only a notebook, a walk, or a quiet evening. Of course, AI has many valuable uses, but perhaps not every vague feeling needs computational power. Sometimes the most environmentally friendly form of reflection is simply thinking for yourself, writing something down, or doing absolutely nothing for a while. -
なぜ私たちは自分を『最適化』し続けるのか 10.09.2026 13минWhy are we constantly trying to optimize ourselves? In this episode, I look at how modern life encourages us to adapt to systems rather than question them. Employees optimize for promotions and performance reviews, while independent creators optimize for algorithms, clicks, followers, and engagement. Even after leaving the office, the logic of evaluation often remains. I also explore what happens when this mindset enters creative work: people search for the “right” titles, topics, styles, and opinions, only to become increasingly similar. Perhaps originality begins where optimization stops, and where we allow ourselves to remain inefficient, strange, and slightly outside the expected answer.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/●Substack日々考えたことや感じたことを自由に書いていますhttps://shigekisaito.substack.com------------------------------------------------------------------------------------------------------ -
なぜ私たちは『相談』ではなく『壁打ち』と言いたがるのか 09.09.2026 12минWhy do people in business increasingly say “sounding board” instead of simply asking for advice? In this episode, I explore my discomfort with the Japanese business buzzword kabeuchi, literally “hitting a wall.” Behind this seemingly harmless expression may lie something revealing about modern work culture: we want other people to help organize our thoughts, but we do not necessarily want their opinions, disagreement, or criticism. I discuss the hidden cost of using someone else’s time, why AI may actually be a more ethical sounding board, and what this trend tells us about our relationship with other people.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/●Substack日々考えたことや感じたことを自由に書いていますhttps://shigekisaito.substack.com------------------------------------------------------------------------------------------------------ -
普通の人間であることが、最も差別化になる時代 08.09.2026 13минIn an age of AI, optimization, and personal branding, being an ordinary human may become a powerful form of differentiation. More people are following the same formulas: quitting jobs, becoming freelancers, building personal brands, exercising, investing in themselves, and using AI to optimize everything. As our content and lifestyles become increasingly polished and similar, imperfect people may become more interesting. Someone who hesitates, changes their mind, wastes time, or follows an irrational obsession can feel surprisingly authentic. In this episode, I explore why “natural” human behavior may become increasingly rare—and therefore increasingly valuable—in an AI-driven world.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/●Substack日々考えたことや感じたことを自由に書いていますhttps://shigekisaito.substack.com------------------------------------------------------------------------------------------------------ -
コンフォートゾーンから出るな 07.09.2026 12мин“Get out of your comfort zone” is one of the most common messages in self-help culture. But is staying comfortable really such a bad thing? In this episode, I question the idea that we must constantly challenge ourselves, improve, grow, and seek new experiences. A comfort zone can also be a place of stability, recovery, and safety—a base we can return to after taking risks. Modern self-improvement culture often makes ordinary, peaceful living feel like stagnation. Perhaps we do not need to escape our comfort zones. Maybe we simply need to leave them when necessary—and return without feeling guilty.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/●Substack日々考えたことや感じたことを自由に書いていますhttps://shigekisaito.substack.com------------------------------------------------------------------------------------------------------ -
Vlogなら物語を作らなくていい、という誤解 06.09.2026 9минVlogs may look simple: just film your daily life, meals, work, shopping, and weekends. But keeping viewers interested over time is much harder than it seems. Once people become familiar with the same room, routines, and places, the novelty begins to disappear. Successful vloggers need to find small stories inside ordinary life—changes, goals, challenges, decisions, and developments that give viewers a reason to return. At the same time, too much staging can make a vlog feel artificial. In this episode, I explore the difficult balance between authenticity and storytelling, and why vloggers are also editors and storytellers.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/●Substack日々考えたことや感じたことを自由に書いていますhttps://shigekisaito.substack.com------------------------------------------------------------------------------------------------------ -
社会の命令を自分の欲望として内面化した人間のほうが、よほど効率よく動く 05.09.2026 13минWhat if modern society no longer needs to give us orders because we have learned to command ourselves? In this episode, I explore how social expectations can become personal desires. We wake up early, exercise, study AI, improve our careers, manage our health, and chase productivity because we believe we freely chose these goals. But did we? The more powerful form of control may be the one that feels like freedom. When society’s expectations become an inner voice, no supervisor is necessary. True freedom may begin when we question whether the destination we are pursuing is really our own.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/●Substack日々考えたことや感じたことを自由に書いていますhttps://shigekisaito.substack.com------------------------------------------------------------------------------------------------------ -
嫌われる拝金主義者と、愛される拝金主義者の違い 04.09.2026 17минWhy are some openly materialistic people surprisingly likable, while others seem deeply unpleasant? In this episode, I explore the difference between desire and hypocrisy. A person who openly admits wanting money, status, luxury, or success can feel refreshingly honest. By contrast, someone who constantly talks about money but reframes every desire as “freedom,” “self-growth,” or “living authentically” may create distrust. Modern audiences are highly sensitive to inconsistency between a creator’s stated values and actual motivations. The real issue may not be greed itself, but the gap between desire, personality, and self-presentation. Authenticity can make even an imperfect character compelling.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/●Substack日々考えたことや感じたことを自由に書いていますhttps://shigekisaito.substack.com------------------------------------------------------------------------------------------------------ -
なぜ自己啓発屋に『真面目に働け』という批判が起こりにくいのか 03.09.2026 14минWhy do online communities built around self-help, side hustles, AI, and “making money online” rarely criticize the people selling these ideas? In this episode, I explore a possible reason: many followers hope to become sellers themselves someday. Criticizing the guru can feel like criticizing their own future. This creates a self-reinforcing cycle where people teach others how to earn, then those students teach the next group. Eventually, everyone may be talking about how to make money while fewer people create anything outside the system. Activity remains high, but real-world value becomes harder to see. At that point, theory itself becomes currency.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/●Substack日々考えたことや感じたことを自由に書いていますhttps://shigekisaito.substack.com------------------------------------------------------------------------------------------------------ -
サラリーマン後遺症 02.09.2026 14минLeaving a company is easy. Leaving the company inside your head can take years. In this episode, I explore what I call “Salaryman Aftereffects”: the habits, fears, and ways of thinking that remain after someone quits corporate life. Employees receive more than a paycheck—they receive approval, structure, roles, and a sense of being needed. After independence, those rewards disappear. Suddenly, no boss gives instructions, no company provides work, and no one praises your efforts. True independence requires learning to decide for yourself, use your skills for your own life, face the market directly, and stop waiting for permission.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/●Substack日々考えたことや感じたことを自由に書いていますhttps://shigekisaito.substack.com------------------------------------------------------------------------------------------------------ -
空理空論バブル 01.09.2026 12минWhat happens when AI reduces white-collar jobs while making it easier than ever to produce professional-sounding ideas? In this episode, I explore what I call the “Empty Theory Bubble”: a world where fewer people do the actual work, while more people talk about how work should be done. AI can generate articles, courses, newsletters, and expert-sounding advice almost instantly, dramatically lowering the cost of producing abstract ideas. The danger is not that these ideas are necessarily wrong. Many are perfectly reasonable. The problem begins when theory replaces experience, and polished language becomes a substitute for actually doing something in the real world.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/●Substack日々考えたことや感じたことを自由に書いていますhttps://shigekisaito.substack.com------------------------------------------------------------------------------------------------------ -
地獄があるから自己啓発は売れる 31.08.2026 11минWhy does self-help sell so well? Perhaps because people feel they are already living in hell. Inspired by Ryunosuke Akutagawa’s famous story The Spider’s Thread, this episode compares self-help, side-hustle courses, AI entrepreneurship, and online business opportunities to threads hanging above people desperate to escape their current lives. When work, money, loneliness, or uncertainty becomes unbearable, even a fragile thread can look like a lifeline. But constantly searching for the next course, method, or opportunity may become a substitute for real progress. Sometimes escaping requires no magical thread—only the slow, unglamorous work of building your own staircase.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/●Substack日々考えたことや感じたことを自由に書いていますhttps://shigekisaito.substack.com------------------------------------------------------------------------------------------------------ -
なぜ中身が薄くても、好感度の高い人物は強いのか 30.08.2026 14минWhy can people with seemingly little substance still become highly popular and successful? In this episode, I explore how appearance, charm, likability, and personality influence the way we judge others—often more than we realize. Drawing on the psychological “halo effect,” social media culture, and a personal experience from my time working in Vietnam, I examine how first impressions can shape opportunities and even create real advantages over time. But there is another side to the story: people we dismiss as superficial may surprise us with unexpected kindness. Perhaps human value is far more complicated than “substance” alone.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/●Substack日々考えたことや感じたことを自由に書いていますhttps://shigekisaito.substack.com------------------------------------------------------------------------------------------------------ -
冷水シャワーは資本主義に優しい苦行である 29.08.2026 11минWhy have cold showers become so popular in modern self-improvement culture? In this episode, I describe them as a form of “light asceticism.” Traditional religious asceticism can involve distancing oneself from worldly desires and ambitions. Cold showers, however, offer just enough discomfort to create a sense of discipline without disrupting everyday life. You can suffer briefly, feel that you have conquered yourself, and then go to work as usual. They can even become a symbol of a disciplined identity on social media. Perhaps cold showers represent a distinctly modern form of suffering: uncomfortable enough to feel meaningful, but perfectly compatible with capitalism.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/●Substack日々考えたことや感じたことを自由に書いていますhttps://shigekisaito.substack.com------------------------------------------------------------------------------------------------------ -
なぜ現代人は友達ではなく仲間を欲しがるのか 28.08.2026 11минWhy do people today seem to want “companions” or “teammates” rather than traditional friends? In this episode, I explore the growing popularity of the Japanese word nakama in self-help communities, startups, and online groups. Friendship can involve deep, open-ended emotional responsibility, while nakama relationships are often connected to a specific goal, project, or community. This makes them flexible: warm enough to reduce loneliness, yet easy to dissolve when circumstances change. But there is also a danger. Communities can demand loyalty and unpaid effort while offering little responsibility in return. Perhaps modern people want friendship that can always be dissolved.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/------------------------------------------------------------------------------------------------------ -
人間は「何者でもない人生」を肯定できるのか 27.08.2026 15минCan we accept a life in which we never become “someone”? In this episode, I begin with Dostoevsky’s Notes from Underground and explore the modern pressure to succeed, build expertise, gain followers, and prove our value to society. Social media has made comparison easier than ever, turning even ordinary life, loneliness, and failure into marketable content. But could AI eventually offer another possibility? Instead of making humans more productive and competitive, perhaps technology could create a society where people no longer need to justify their existence through work, status, or achievement—a world where becoming “someone” is a choice, not an obligation.------------------------------------------------------------------------------------------------------●ビジネス日本語学習者のための無料メルマガ講座https://my162p.com/p/r/odSmegng●ビジネス日本語学習者向けブログビジネスのために日本語を学んでいる人のための情報を発信していますhttps://businessnihongo555.blogspot.com/------------------------------------------------------------------------------------------------------
