Modern Ronin Reflections
From my own experience, I have gradually realized that what truly exhausts a person is often not the external world itself. But rather: * internal conflict * fragmentation * anxiety * excessive concern about others’ opinions * living constantly through a persona When energy continuously leaks outward, the mind becomes unstable, scattered, and psychologically weak.

《浪人劍客》中宮本武藏早期的執念與轉變 最近看到《浪人劍客》前期， 尤其是寶藏院那一段時， 我突然理解了一件很深的事情： 宮本武藏早期對「變強」的執念， 其實並不是真正的強。 而是一種來自內在匱乏與外部評價的渴望。 年輕時的武藏， 腦中只有一件事： 「我要變強。」 「我要天下無雙。」 因此他的邏輯非常簡單粗暴： 只要打倒所有強者， 只要把所有人都擊敗， 那麼自己就應該是最強的人。 這是一種非常原始、 非常野獸性的強。 但從心理學的角度來看， 這其實隱藏著一個巨大的問題： 他的評價機制是外部的。 他並沒有真正建立自己的內在價值系統。 因此， 當別人問他： 「那你覺得你自己強嗎？」 武藏竟然回答不出來。 這一幕其實非常震撼。 因為這代表： 他根本不理解什麼叫做真正的強。 他只能透過： • 別人的恐懼 • 別人的稱讚 • 別人的敬畏 • 別人的認可 來確認自己的存在。 所以哪怕他真的殺光所有強者， 成為天下第一， 他依然是奴隸。 因為他的內心， 仍然被「外部評價」所控制。 只要一個人的價值感， 建立在他人的眼光之上， 那麼他就永遠無法自由。
Modern Ronin Reflections
Each of us is born into a culture by accident. Nationality, ethnicity, religion, and identity are often not conscious choices, but conditions assigned at birth. Therefore, the healthiest relationship between human beings and culture should not be one of obedience or psychological captivity. Instead: Human beings should have the freedom
Modern Ronin Reflections
What resonates with me most about Miyamoto Musashi is not merely his solitude. It is this: He once seriously considered becoming part of the world. As a young man, Musashi also desired: * recognition, * honor, * status, * achievement, * and the possibility of serving a lord. He was not born detached from society.

In 2022, I walked away from a stable job in Taipei, Taiwan. At the time, I was working as a PM for Rockwell Automation products at Solomon Technology. From the outside, it looked like a safe and respectable career path. But deep inside, I kept hearing a quiet voice: “This

I’ve come to realize that many creators, artists, and thinkers begin to “converge” as they reach their forties. Not toward conformity — but toward clarity. When I was young, studying at Taipei Institute of Technology, I never fully fit into the traditional education system. I disliked rote learning and standardized
Modern Ronin Reflections
I have long felt that modern society teaches us a deeply misleading idea: “The inner matters more than the outer.” I believe this is incomplete. The truth is not that the inner is more important than the outer. The truth is: the inner and the outer matter equally. Because your

The older I get, the more I realize that silence is the language of the strong. When a person becomes internally aligned, they begin to feel the movement of energy very clearly. And language itself is a release of energy. You start noticing that whenever you constantly try to explain

Today, my wife asked me an interesting question. She asked: Germany and Japan are both world-class nations known for craftsmanship, engineering, and quality. So why do they feel so different? I thought about it for quite a while. And I realized: Although both Germany and Japan pursue precision, quality,

At the age of forty-four, I revisited Dragon Ball Z and finally understood what it truly meant. It was never just a story about fighting. It was about: growing stronger in solitude. What made Goku, Gohan, and Vegeta inspiring was never simply their power. It was this: Even knowing

I have always felt that Japanese culture carries a unique kind of beauty — a beauty that is both elegant and tragic. It is a beauty born from impermanence. Sakura blossoms are breathtaking not because they last forever, but precisely because they are destined to fall. The spirit of Bushido carries

Fifteen years later, I returned to this small izakaya. The posters were still there. The warm lights, the wooden walls, the atmosphere — unchanged. Back then, I had just graduated from graduate school. I worked in Nangang Software Park during the day, and at night, I often came here alone with
