Uncovering your own strengths and weaknesses is tough. In Chinese-speaking culture, it’s rare to hear someone genuinely praise a specific skill of yours. In fact, I often observe a tendency where people self-deprecate just to avoid seeming ostentatious. I’ve always been that kind of person, too, but recently I've been trying to change.

Thoughts on "The Worst Kind of Programmer"
Reflections after reading "The Worst Kind of Programmer." This post examines the perils of over-engineering in software projects and how it undermines long-term team productivity. Great engineering prioritizes simplicity and just-enough solutions over the premature adoption of trendy tech. Highlighting the importance of code that is easy to maintain and modify, the article also emphasizes effective communication in technical decision-making. Drawing on Jeff Bezos's "disagree and commit" principle, it encourages teams to move forward even amid differing opinions, while avoiding compromises that lead to suboptimal Frankenstein solutions.

Thoughts — Learning Management from Games
The original article was written in Japanese, but it contains many points that resonated with me at work and even things I can learn from. Therefore, I decided to quote it briefly and share my own thoughts here. The author is 36 years old. Formerly an engineer, he stepped into a management role because he was getting older and gradually losing his passion for technology. Right around that time, his boss said, "Why don't you give it a try?" The pay went up, so he went along with it and took the position. Amusingly, the author says, "There's just one problem: I hate people the most. If possible, I prefer being alone. Why would I want to manage people when things were going fine?" Anyway, there were no sales targets to worry about, the paycheck was coming in, so he figured he might as well do it properly.

Every time I run `npm install` on a MacBook Pro or an iMac, the fans kick up to full blast.
