Modern Ronin Reflections is a collection of essays on engineering, learning, discipline, and life from Dr. Jack Yeh, exploring the mindset of a modern-day ronin.

Discomfort and frustration are not obstacles to growth — they are part of the process. Learning to accept them, and even becoming comfortable with them, is what allows continuous improvement and long-term compounding. From my personal experience, compounding growth is often counterintuitive to human nature. Most people naturally seek comfort

A strap often interrupts that clarity. That’s why I prefer a hand-carried bag. It may be less convenient, but it preserves the discipline of the silhouette. To me, style is not display. It is restraint and proportion. 男裝的關鍵在於線條與比例。 背帶往往會打斷這種俐落感。 所以如果需要帶包，我更喜歡手提包。 它或許不那麼方便，但能保持造型的簡潔與平衡。 對我來說，風格不是炫耀，而是克制與比例。

I have noticed that many people simply stop caring about their appearance and their body. They stop exercising, stop grooming themselves, and slowly become indifferent to how they present themselves. But I believe that a sense of beauty and self-care are deeply important. If a person cannot appreciate the

I believe that the pursuit of beauty and elegance should begin the moment we become conscious of ourselves, and continue until the day we leave this world. Beauty and elegance are not merely superficial decorations. They are, in many ways, a resistance against entropy. Without conscious effort, people naturally drift

Self-awareness matters because without it, your life can easily be taken over. Culture, ideology, morality, and collectivism all have the power to shape how people live. When a person lacks awareness, these forces quietly become the operating system of his life. Most people never notice this happening. They simply

Life is rarely something that can be planned in advance. Many people believe that life should be designed through goals and detailed plans. But in reality, the future cannot be predicted or engineered in that way. From the perspective of Buddhism, the nature of the world is causality and conditions.

Much of the anxiety people feel in the age of AI comes from a deeper habit in human civilization. For a long time, humans have been trained to see themselves as tools. After the industrial revolution, this mindset became even stronger. People began defining themselves through professions, job titles, and

When manga artist Inoue Takehiko created Vagabond, he was not simply telling the story of Miyamoto Musashi. For him, the work was also a personal journey—an exploration of a deeper question: What does it truly mean to be strong? In the early stages of the story, Musashi believes that

In the world of engineering and knowledge, true strength is not about defeating others. True strength lies in how deeply you understand your field. Do you truly understand the principles? Can you explain them clearly? Can you see through the essence of the problem? This is why I strongly advocate

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
Modern Ronin Reflections
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
