The Meaning of Strength

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 strength means defeating others in duels and proving himself through victory. But as his journey unfolds, he gradually realizes that true strength is not merely about overcoming opponents, but about the continuous refinement of oneself.

For me, strength has never been about comparing myself with others.

True strength is comparing yourself with who you were yesterday.

If today you are a little better than yesterday,

and tomorrow you are a little better than today,

then growth begins to accumulate—just like compound interest.

Over time, mastery becomes not a question of talent, but simply a matter of time.

This philosophy is also the reason why I created YEHSTALK.SCHOOL and why I dedicate myself to teaching and sharing knowledge.

My goal is not only to teach engineering techniques, but to help my students and fellow engineers become stronger.

Not only stronger in skills,

but stronger in mindset.

Beyond motor control and engineering knowledge, I hope they learn a way of thinking—a mindset of continuous growth.

To improve a little every day,

and allow progress to compound over time.

When that happens, each person can walk their own path and eventually become a truly strong engineer.

漫畫家井上雄彥在創作《浪人劍客》時，其實不只是描繪宮本武藏的一生。

對他而言，這部作品更像是一場內心的探索——他試圖透過武藏的旅程，去回答一個問題：什麼叫做真正的「強」？

在故事的早期，武藏認為「強」就是擊敗別人、在決鬥中勝出。但隨著旅程的推進，他逐漸理解到，真正的強大並不只是戰勝對手，而是一種不斷修行自我、持續成長的過程。

對我來說，「強」從來不是和別人比較。

強，是和自己比較。

如果今天的自己，比昨天更好一點；

明天的自己，又比今天更進步一點；

那麼這樣的成長就會像複利一樣不斷累積。

當這樣的進步持續下去，成為真正的大師，其實只是時間的問題。

這也是我創立 YEHSTALK.SCHOOL、製作課程與分享知識的原因。

我的目標不只是傳授技術，而是讓我的學生、學員與工程師朋友們變得更強。

不只是技術上的強，更是一種心態上的強。

我希望他們學到的不只是 motor control 的知識，

更是一種強者的思維方式——

每天進步一點點，

讓成長透過時間與複利持續累積。

最終，每個人都能走出自己的道路，成為更強的工程師。
