Modern Ronin Reflections
For a long time, I’ve had a persistent sense that everything we achieve in life— degrees, titles, awards, milestones— feels very similar to progress in a video game. It is as if we are controlling a character, leveling up, clearing stages, and occasionally collecting rewards along the way. But
Modern Ronin Reflections
Why is long-term thinking essential for career success and personal growth? Because only over a long enough period can compounding truly take effect. Compounding is not an instant force. It is a kind of alchemy that requires time to build, deepen, and multiply. Without time, there is no real
Modern Ronin Reflections
Many people like to say: “Never forget your original heart.” It sounds beautiful, even inspiring. But the more I reflect on life, the more I feel that this idea is not always true. In some cases, it can even become a kind of toxic comfort. Why? Because the human heart
Notes
I’ve spent many years outside the system. Doing the work that matters,building systems that function,and making things clear. Recently, I was recognized as an IEEE Senior Member. I’m genuinely happy about it.And I would like to thank three international experts for their trust and support
Modern Ronin Reflections
For me, I have already accomplished many things in life. I earned a Ph.D., worked in Taiwan for more than a decade, built my own business and channel, and wrote my English Springer book. My green card has also been approved. So if I still want to challenge myself
Modern Ronin Reflections
After forty, I gradually went through a deep process of self-integration. If I borrow Carl Jung’s language, it was something like shadow integration. After going through that path, I found that death began to enter my thinking naturally. It was not negativity, and it was not pessimism. It
Modern Ronin Reflections
Like Miyamoto Musashi, a ronin who walked his own path with two swords, I see myself as a modern ronin. One blade is engineering. One blade is philosophy. Engineering reduces uncertainty and builds stable systems. Philosophy reduces inner noise and builds a stable mind. They appear different, but at their

The world does need strong theory. What it needs even more is the ability to turn theory into working systems. Engineering is not only about understanding — it is about bringing ideas into reality. Understanding gives us direction. Execution gives that direction form. And even realization is not the end. Greater
Modern Ronin Reflections
Recently, I’ve come to realize that life is essentially a process of using energy. Everything we do is an expression of how we use energy. But the key is not whether we have energy— it’s how that energy is generated. When you are aligned with your inner self,
Modern Ronin Reflections
The fastest way to stop anxiety is to turn off the switch of comparison. Whether you compare yourself to others or to a future version of yourself, comparison always creates anxiety. The moment you turn that switch off, anxiety disappears. But what truly matters is this— once anxiety is gone,
Modern Ronin Reflections
I’ve come to resonate with an idea often associated with Carl Jung: Without touching something transcendent, a person cannot truly experience meaning in life. This sense of transcendence does not come from material accumulation or external achievements. The material world is finite, but the human psyche seems to reach
Modern Ronin Reflections
Language and words are, by nature, tools of highly compressed information. They exist to make complex experiences communicable, but in doing so, they inevitably lose a vast amount of detail. For this reason, it is impossible to truly understand life through language alone. Language can describe experience, but it can
