焼畑ビジネスで気を付けなければならないポイント 21.09.2026 11นาทีHow can you tell whether a business opportunity is already burning out? In this episode, I examine “slash-and-burn” business models, especially those built around teaching people how to make money online. The early entrants may succeed, but problems arise when students become sellers of the same methods and the market depends on a constant supply of newcomers. I discuss several useful questions: Who is the final consumer? Does the product have value without being resold? How many people actually succeed? What did the successful people sell? Sometimes a market looks prosperous only because yesterday’s success stories are still being advertised. -
自己啓発産業のサプライチェーン 20.09.2026 13นาทีWhat if the self-help industry has its own supply chain? In this episode, I look at self-help through the lens of manufacturing. Ideas such as mindset, personal branding, resilience, and journaling are imported, translated, adapted, shaped into familiar formulas, mass-produced as social media posts, and distributed to consumers. Some creators act like trading companies, others like mold makers, factories, wholesalers, or retailers. This does not mean self-help is worthless. The more interesting question is where value is added, where ideas become diluted, and where they turn into copies. Perhaps every motivational idea has its own manufacturing history. -
現代人は、人生を攻略ゲームに変換することで、不確実さから逃げているのではないか 19.09.2026 12นาทีWhy are modern people so obsessed with optimization? In this episode, I explore the possibility that optimization helps us cope with uncertainty. Life has no clear roadmap, but goals, numbers, routines, and success formulas can make it feel like a game with rules. We want success to have a reason and failure to have an explanation because randomness is uncomfortable. Yet effort does not always produce results, and success may depend partly on timing, circumstances, and luck. Perhaps we do not need more strategies for mastering life. What we need instead is the ability to live in a world that cannot be fully mastered. -
自己啓発屋の思想はなぜテフロン加工されているのか 18.09.2026 17นาทีWhy does self-help thinking sometimes seem Teflon-coated? In this episode, I explore how certain ideas appear designed to repel criticism, failure, social problems, and even self-doubt. When reality challenges the message that “everything depends on you,” another positive slogan can simply provide a fresh coating. I contrast this with a “wok-style” philosophy: scratched, burned, blackened, and shaped by direct contact with reality. Perhaps good thinking should allow failure, contradiction, other people’s suffering, and uncomfortable facts to stick. There is nothing wrong with ambition or desire. But when desire is sticky while criticism slides away, something strange begins to happen. -
空手形ばかり切るビジネス 17.09.2026 8นาทีIs modern self-help built on promissory notes? In this episode, I explore how online businesses often sell promises whose value can only be judged in the future: change your habits and your life will improve, invest in yourself and you will succeed, or build systems and you will become free. On social media, people even seem to endorse each other’s promises through likes, comments, and mutual praise. But eventually, every promise reaches its maturity date. What actually remains after one, two, or three years? Perhaps sustainable business is less about selling grand dreams and more about delivering small, concrete value today. -
働きすぎる社長は、本当に優秀なのか 16.09.2026 11นาทีIs a CEO who works constantly really a great CEO? In this episode, I explore the difference between working hard and actually managing a company. During the early stages of a business, founders often need to do everything themselves. But as a company grows, the skills required may change. Executives must learn to delegate, step away from daily operations, think about the future, and sometimes simply wait. Practical tasks feel satisfying because they have clear endings, while strategic thinking often produces no immediate result. Perhaps great management is not about staying endlessly busy, but knowing when to work, delegate, think, and do nothing. -
人畜無害はノーリスク・リターンな徳である 15.09.2026 13นาทีIs 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 11นาทีWhat 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 11นาทีWhat 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 11นาทีWhy 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 10นาทีIs 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 13นาทีWhy 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 12นาทีWhy 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 13นาทีIn 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 12นาที“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 9นาทีVlogs 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 13นาทีWhat 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 17นาทีWhy 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 14นาทีWhy 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 14นาทีLeaving 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------------------------------------------------------------------------------------------------------
