Modern Ronin Reflections
In the end, every human being will die. No matter how much success, fame, or wealth one accumulates, time will eventually take everything away. In Buddhism, this is known as impermanence. The Stoics remind us to remember death— memento mori. Existential philosophy tells us that each person must ultimately face

I have always believed that the strong never explain themselves. If you know exactly what you are doing, there is no need to explain it to anyone. Those who understand you need no explanation. Those who don’t will never truly understand. In reality, many people feel the urge to

When we observe the current development of AI, the real bottleneck is not chips. It is energy. Training modern AI systems requires enormous amounts of power. AI can dramatically increase economic productivity, but that productivity ultimately depends on energy. In the long run, it’s all about energy. From the

Many people believe that a book should be read from the first page to the last. But in my experience, a book can be read from beginning to end, or it can be read selectively. Because a book is written by a human, and human knowledge is rarely indivisible. Yet

It is almost impossible for a person to live without labels. Our names are labels. Our professions are labels. Even our culture and nationality are labels. So the real question is not whether labels exist, but how large they are. Some people choose to define themselves within a small pond—

Real happiness does not come from comfort. It comes from overcoming something difficult. Without struggle and growth, life would lose much of its joy and meaning. 真正的快樂 並不是來自於舒適。 它來自於克服困難的那一刻。 如果人生沒有痛苦與成長， 生活就會少了很多 樂趣與意義。

Meditation has helped me realize something very clearly: I am not my brain. I am not the thoughts in my mind. I am not my emotions. I am the one observing all of them. Once you see this clearly, you begin to realize that many thoughts are just noise produced
Today I received the birthday gift I prepared for my wife. A cordovan long wallet from Tsuchiya Kaban, a Japanese leather craftsmanship brand. Cordovan leather is polished to a mirror-like finish, giving the surface a deep and refined shine. Holding it in hand, you can immediately feel why Japanese

My wife often asks me why I’m not interested in collecting things the way many men do—cars, figures, or other collectibles. I usually tell her that I might be a little different. I don’t really like collecting objects, because to me, objects are lifeless. In the end,

I often find myself reflecting on a question. In a cultural framework shaped largely by Confucian ethics, social relationships are traditionally organized around hierarchy and obedience. Among the Five Relationships, only friendship approaches equality; the others are structured as superior-to-subordinate relations. If the underlying structure of a culture

In many cultures influenced by Confucian traditions, filial piety is treated as a fundamental virtue. Children are constantly reminded of the sacrifices their parents made and are expected to repay that “debt.” But this raises a deeper question. Before parents bring a child into this world, the child was never

Through mindfulness meditation, one can clearly see a simple truth: the thoughts and emotions that arise in the mind are not who we truly are. During meditation, you can observe thoughts appearing and disappearing, and emotions rising and fading. What can be observed cannot be the observer. Isn’t this
