A Journey through My Diverse Perspectives

  Knowing what is “enough” is important at every stage of life, but it becomes especially vital after retirement, when we begin reassessing our purpose and no longer feel the need to chase goals with the same urgency. Cultivating this sense of contentment starts with gratitude—appreciating the circumstances we are in and the things already within our reach. We can deepen this gratitude by practicing it consciously each day and making it a natural habit. Through regular inner dialogue, we can also clarify what truly matters, organize our priorities, and act on them in a steady, purposeful order. When we focus on what is within our grasp and approach it with gratitude, we free ourselves from comparison and envy. In doing so, we find a quiet satisfaction, along with a deep sense of peace and happiness.

  Yoichi Takahashi (1955–), a former Japanese government cabinet counselor and quantitative policy scholar, possesses extensive expertise in economics, diplomacy, and finance. In his book Introduction to Economics , he emphasizes that a single supply-and-demand diagram can explain nearly 90% of economic conditions and policies, including fiscal and monetary measures. Takahashi argues that this diagram is not only the simplest but also the most versatile tool in economic theory. By applying it to real-world examples and thinking independently, individuals can make practical use of its insights. He further suggests that theoretical knowledge can be one of the most powerful tools for ordinary people seeking to navigate their economic lives. Although this example comes from economics, it is wise for individuals to understand, test, and internalize simple, adaptable theories and principles that reflect accumulated human wisdom. Doing so, I believe, is an essential part of leading a wise...

  Konosuke Matsushita (1894–1989), the renowned Japanese businessman, once said that if we believe each person has a unique mission in life, we will no longer feel envious or critical of others. When we think this way, comparison becomes unnecessary, and our attention naturally shifts to whether we have grown—focusing on who we are today rather than who others are. Matsushita also emphasized the importance of trusting the quiet voice that arises from deep within the heart, a reminder that we are meant to live our own lives, not measure ourselves against anyone else.

  Humans naturally seek independence—the ability to think and act on their own. Yet we are also social beings who depend on relationships, influence, and cooperation. Without these connections, true independence cannot develop; and without personal independence, meaningful relationships cannot form. This dynamic mirrors the link between a single fish and a school, or between individual cells and the human body. Seen this way, living well both for ourselves and for others is essential, for neither society nor individual lives can function without this balance.

  When proposing and implementing a large project, we must balance boldness with precision. In the early stages, boldness shapes the project’s overall scale; without it, an initiative may shrink into something ordinary and overly cautious. But when we show the drive to pursue ambitious goals despite some uncertainty, we are more likely to gain the support of key people inside and outside the organization. As the project advances, precision becomes essential. Careful planning and attention to detail ensure that ambitious ideas are carried out effectively. It is like digging a hole: we begin by digging wide—boldness—and then dig deep with accuracy—precision.

  During my walks, moments of unexpected beauty—whether a striking natural scene, a stunning flower, or a newly discovered path—fill me with a deep sense of fulfillment, as if I’ve received a spiritual gift without spending anything at all. This morning’s walk offered all three, and I was especially moved by the sight of a small child joyfully chasing falling yellow ginkgo leaves, glowing in the morning sun as they danced in the wind. It reminded me that such blessings can only be felt when we have the mental space to be present in the moment.

  Kiyoshi Oka (1901–1978), the Japanese mathematician known for his foundational work in several complex variables, left behind many memorable sayings. One of them is: “Even if something doesn’t interest you, or even if it seems unappealing at first glance, it’s worth facing it with determination and focus. When you do, you’ll find parts of it that you can come to like.” When I was working in an office, I was often assigned tasks I didn’t enjoy. Yet by choosing not to sulk and instead immersing myself in the work, I learned new skills, improved my efficiency, and even proposed additional ideas that added value. In doing so, I found ways to enjoy the work and put those insights into practice. Because of that experience, Oka’s words resonate with me deeply. If you cannot avoid something that doesn’t interest you, the key is to accept the situation calmly and engage with it proactively. Doing so can lead to new discoveries, fresh perspectives, opportunities for growth, and unexpected ...
