A Journey through My Diverse Perspectives

  When we are suddenly confronted by hardship or adversity, discovering a deeper meaning that resonates with our lives can help us regain emotional balance and cultivate the wisdom and resilience needed to move forward. In reality, however, most people become overwhelmed in such moments; consumed by the apparent unfairness or absurdity of their situation, they often lose the composure and inner strength needed to overcome the challenge on their own.

  A walk offers a precious opportunity to engage in a dialogue with oneself. By letting go of regrets about the past and anxieties about the future, and simply walking while focusing on the present moment and observing the surrounding nature, we can acknowledge and appreciate ourselves, cleanse our minds, and reconnect with our innate positive spirit. Even a brief walk, when approached mindfully, can bring unexpected mental benefits.

  In astrophysics, the dust and gas produced by supernova explosions contain elements such as hydrogen, helium, carbon, and oxygen. Since these elements eventually became part of Earth and gave rise to all terrestrial life, including human beings, we are often described as being made of stardust—a reminder that we are, in a very real sense, part of the cosmos. Remarkably, researchers have also noted intriguing similarities between the network structure of neural circuits in the human brain and the large-scale structure of the universe, with its countless galaxies, black holes, etc. Inspired by such parallels, some astrophysicists and philosophers have suggested that the universe, through curious and imperfect human observers, is gradually coming to know itself. Over mere decades and centuries, humanity has uncovered tiny fragments of a cosmos that has existed for approximately 13.8 billion years—an astonishing pace when viewed against cosmic time. Whether or not this vision is lite...

When we have something to look forward to in the near future, it gives us emotional encouragement. It becomes easier to endure the small hardships of daily life while inspiring us to make the most of each day until that moment arrives. For example, planning a trip to a country you have never visited and anticipating its culture and natural beauty can become a meaningful source of motivation. If your daily routine has left you feeling overwhelmed or emotionally drained, try setting a goal for something you genuinely look forward to and plan to make it happen within the coming months or year. Even alongside small daily pleasures, having such a future event to anticipate can lighten your heart and renew your spirit.

  Whether it is a once-in-a-century discovery by a great thinker that brings immense benefit to humanity or a profound insight that illuminates the life of an ordinary person, such achievements emerge from persistent reflection on essential, deep, and genuine questions, combined with opportunity and circumstance. This reminds us of the importance of wrestling with our own authentic questions about what truly matters, rather than settling for the trite, ready-made answers of others. In an age of rapid AI advancement, this uniquely human capacity is being tested—and valued—more than ever.

  Since retiring, my wife and I have made it a daily habit to walk around our neighborhood. To keep the routine from becoming monotonous, we vary our route each time, and occasionally drive 10 to 15 minutes to a nearby park or other pleasant place for a change of scenery. One of our favorite destinations is a lush municipal sports center about ten minutes from home, where we sometimes enjoy walking along the surrounding paths. Yesterday and today, however, we tried something different: instead of walking outdoors, we exercised in the center’s gym and used several pieces of fitness equipment. It was my wife’s first visit to a gym, and for me, it had been more than a decade. We both approached the experience with fresh eyes and discovered that we had more physical stamina than we had expected, which gave us renewed confidence. It was also fascinating to realize how differently we viewed the same sports center simply because our purpose had changed. A familiar place can feel surprisin...

  Throughout my career, I devoted myself to acquiring the practical knowledge and skills needed to achieve meaningful results. After retiring, however, I gradually drifted away from my professional field, and my interests naturally expanded to broader subjects such as history and physics. There is a quiet joy in discovering, one by one, things I had never known before and satisfying my pure intellectual curiosity. That feeling resembles the deep contentment of enjoying a truly satisfying meal. As a citizen, I also remain interested in politics, economics, diplomacy, and national security. Yet these fields are deeply shaped by conflicting human interests, values, and ambitions. Even when I gain new knowledge in those areas, it rarely satisfies my intellectual curiosity in the same way, because the issues are shaped less by universal principles than by conflicting human interests and values.

  From the expansion of the universe to the fluctuations of elementary particles, the world we inhabit is filled with profound mystery and astonishing precision. It is hard not to marvel at the laws and order that govern it all. Yet we go about our daily lives largely unaware of this, focusing instead on the narrow confines of our routines, where our emotions rise and fall with the ordinary events before us. In truth, however, we exist between the ultra-microscopic and the ultra-macroscopic realms. Simply recognizing that our lives unfold within this miraculous space brings a quiet sense of awe and spiritual clarity.

  While I have no scientific evidence to support this, reflecting on my own life and watching interviews with older adults has led me to believe that people who habitually say, “I’m too old,” often seem to age more quickly—both physically and mentally. By the time they reach their fifties and beyond, they may appear and think noticeably older than many of their peers. In contrast, those who pay little attention to their age, remain deeply curious, and creatively enrich their daily lives sometimes appear more than a decade younger than others of the same age, even in their eighties or nineties. While many factors influence how we age, these observations suggest that our mindset plays a powerful role in sustaining the inner vitality needed to live a vibrant life.

  Through simple acts of kindness, anyone can offer others moments of “Ikigai”—a sense of purpose or something to live for. For example, taking elderly residents who are largely confined to their care facility on a short drive to enjoy the beauty of nearby forests, rivers, or parks can provide a welcome change of scenery. Even an outing of little more than an hour allows them to step away from the healthy yet monotonous routine of daily life, lifting their spirits, refreshing their minds, and renewing their sense of “Ikigai.” This is just one example, but whenever we have the opportunity to bring meaning to someone else's life—offering our time and care freely, without expecting anything in return, and in a way that remains sustainable—it is in those moments that we truly shine as supporting characters, even while remaining the protagonists of our own lives.

  We are naturally drawn to—and often admire—people who live vibrantly, enriching their daily lives with courage and ingenuity despite the limitations they face. Their example inspires us to emulate, at least in part, the spirit of their way of living. A Japanese proverb says that children grow up by watching their parents' backs, and the same psychological dynamic quietly shapes us throughout life.

  We are all the protagonists of our own life stories. Within the various constraints of our circumstances, and through our interactions with the supporting characters around us, we shape a unique narrative that is ours alone. At the same time, the people who seem to be supporting characters in our lives are protagonists in their own stories. From their perspective, we are the supporting characters, helping them reveal their strengths and enrich their own narratives. Seen this way, the relationship between protagonist and supporting character is one of mutual interdependence. The roles simply change depending on whose story is being told. When we positively influence others in our supporting roles, that kindness and encouragement often return to us when we become the protagonists in our own moments. If we hope to create a truly fulfilling life story, we should strive not only to be good protagonists but also to be good supporting characters in the stories of others.

  Envy is a feeling anyone can experience. Even older people—who have accumulated a lifetime of experiences and are expected to be emotionally mature—still feel envy from time to time, though perhaps less often. Naturally, as an elderly man, I am no exception. Envy arises from a complex mix of emotions, rooted in human desires and a sense of inadequacy over things we long for but do not yet have. Left unchecked, these feelings can undermine our self-esteem. So how can we overcome this inner conflict? Simply trying to suppress envy often has the opposite effect, making it even stronger. Instead, by calmly examining our feelings, identifying what we truly desire, and setting realistic goals that reflect our present circumstances, we can gradually release our fixation on those we envy and redirect our energy toward our own growth. In doing so, envy becomes not a burden but a guide, pointing us toward a more purposeful and fulfilling path.

  There comes a time in many people’s lives when they feel a desire to give something back to the society in which they were born and raised—and from which they have benefited in so many ways—by helping to make it a better place. Yet many have likely experienced the moment when, after pausing to take a calm, objective look at themselves, they felt deeply discouraged by the realization that the influence of a single individual is limited. Even so, rather than waiting for someone else to bring about change, we should believe in our own potential, reflect on our strengths, identify where we can make a difference, and take action—even if it begins with changing ourselves. If we find meaning in those efforts, then continuing them while striving to improve their quality becomes truly worthwhile. In time, others who resonate with the spirit of those actions will begin to emerge one by one, and like ripples spreading across a pond from a single stone, their influence will quietly but stead...

  In daily life, there are things we must do, whether we like them or not. However, when these obligations—carried out with a sense of reluctance—occupy a large portion of our days for an extended period, the mental burden can gradually grow, causing our outlook to become increasingly negative without us even realizing it. Once we make progress on these “must-dos” and gain some free time, creating a greater sense of mental ease, it is important to begin consistently pursuing the “things we want to do” that genuinely excite and inspire us. By setting meaningful goals and looking forward to these activities, positive emotions can gradually outweigh negative ones, helping to ease the burden associated with our obligations and bringing greater balance and fulfillment to our lives.

  When we put into action something we have vividly imagined in our minds, it often turns out well—especially when the task is somewhat familiar. When things do not go as planned, it is often because our mental image lacked sufficient clarity or detail. For example, when attempting something for the first time, we may overlook subtle nuances or miss a crucial step in the process. Naturally, the less familiar we are with an experience, the more difficult it is to imagine it accurately. However, through action, trial and error, and repeated experience, we learn not only intellectually but also through our five senses, making our mental images increasingly vivid and realistic. Creative ideas that arrive like flashes of inspiration may emerge from a realm beyond ordinary imagination. Yet transforming those ideas into reality ultimately requires the power of imagination. Viewed in this way, the ability to imagine—especially with a positive mindset—is essential not only in business but i...

  The lacecap hydrangea has a truly unique structure. What appear to be its large outer petals are actually sepals. By developing these large, vividly colored sepals, the plant attracts insects to the cluster of small, inconspicuous hermaphrodite flowers at its center, thereby promoting pollination. In other words, the lacecap hydrangea invests a significant amount of nutrients in a few sepals, creating the appearance of a single large flower and efficiently ensuring the continuation of its seeds to the next generation. The delicate sepals support and highlight the modest flowers at the center, creating a sense of humility while maximizing the effectiveness of the whole plant through mutual complementarity. Leaders can learn much from the lacecap hydrangea. Just as its different parts work together to achieve a common purpose, organizations composed of diverse individuals thrive when each person’s unique strengths are recognized, supported, and combined in ways that enhance the suc...

  There are individuals who possess an exceptional ability to anticipate future developments by carefully considering both past events and present circumstances. Naturally, such people are extremely rare in any field. They consistently demonstrate outstanding powers of observation, analysis, and insight—qualities often grounded in extensive and profound practical experience. If, through observing and verifying a person's words and actions on various matters over months or even years, you come to recognize the existence of such an individual—even if they are not personally close to you—that person can become a remarkable teacher who contributes greatly to your personal and professional growth.

  I often read famous quotes born from the experiences of great people, nod in agreement, and try to express the same ideas in my own words. Yet somehow, those words do not resonate with me or feel entirely genuine. I believe this is because, while we may intellectually understand another person's wisdom, it does not truly become our own unless we have gone through a similar experience ourselves. Without that lived experience, even carefully rephrased words can lack conviction and persuasive power.

  There is something deeply captivating about people who live their ordinary days with thoughtfulness and care, always finding ways to make the most of them. Such individuals naturally inspire both admiration and a touch of envy. If you look around with an open mind, you will surely find people like this in your own life.
