Modern Ronin Reflections
You are already whole. You do not need growth or achievement to become valuable. The problem is that most people forget this, and begin to chase, compare, and fall into FOMO (Fear of Missing Out). But that is an illusion. You don’t need to go through every form of
Modern Ronin Reflections
Many things are right—but not right for you. Many forms of growth are valuable—but not yours to pursue. The real difficulty in life is not doing too little, but wanting everything. The moment you learn to choose— what to let in, and what to let go— you begin
Notes
Control is not tuned — it is modeled. — Dr. Jack Yeh In traditional motor control design, many engineers rely heavily on tuning. But tuning alone cannot reveal the true nature of a system. What truly defines a control system is not how it is tuned, but how accurately it is modeled.
Modern Ronin Reflections
In Taiwan, working on motor drives often means doing two things at once: developing control algorithms and writing firmware. But over time, I’ve come to realize something very clearly— these two tasks use fundamentally different modes of thinking. When I’m working on control theory—deriving models, designing observers—
Modern Ronin Reflections
When you are lost in the mountains, speed is not your advantage. If your direction is wrong, the faster you run, the farther you move away from the right path. In the age of AI, this effect is amplified to the extreme. AI enables rapid execution, continuous output, and the
Modern Ronin Reflections
I believe that as long as a person is willing to question and think critically with logic, they are already an independent thinker. Independence does not necessarily require building an entirely new system. Not everyone has the depth or capacity to reconstruct one. But one thing is certain— every form
Modern Ronin Reflections
I have come to believe that true independent thinking is inseparable from critical thinking. I have never seen a truly independent thinker who does not question or challenge. Because the moment we stop questioning, we are simply operating within frameworks given by others. Growth often begins at the very point
Modern Ronin Reflections
Whenever I become overly eager in pursuing a goal or overly attached to a particular outcome, a subtle discomfort arises within me. It is easy to overlook, but through mindfulness practice I can notice it quickly. To me, this feeling is an important inner guidance. It reminds me that I
Notes
A super individual is not created by AI itself. AI simply lowers the cost of iteration. A super individual is not defined by talent or tools, but by the ability to compound learning through high-frequency iteration. When learning becomes interactive, mistakes can be corrected multiple times a day, and
Notes
I’ve gradually realized something about happiness. Buying expensive things doesn’t really bring lasting satisfaction. For me now, the only thing that truly brings fulfillment is learning. Once I became accustomed to the discomfort and frustration that come with learning something difficult, I started to recognize them as signals
Notes
Time does not automatically work in your favor. This is something I’ve come to understand through my own life and career. A sentence I often remind myself is: If you are not compounding, time is not your friend. Most people assume that time alone will bring progress. But time,

During our trip to Kyoto and Osaka, I brought back not only memories, but also two gifts that I truly love. Both were gifts from my wife. One is a silver ring from the Japanese brand Lord Camelot, designed like a knight’s shield with a fleur-de-lis motif.
