This review resonates with me, so it stays in my heart even more. 😊 I also had a time in the past when I was designing alone without a senior mentor. I had no one to ask, and I wasn't sure if I was on the right track... I especially remember that it wasn't easy to organize design systems or structural parts on my own. That's why when I was creating this lecture, I think I paid more attention to delivering the information easily, with the mindset of helping myself from those days. Hearing that you understood it right away makes me truly happy, as it feels like my intention was well-conveyed. The fact that you felt the design system concepts being organized and naturally connecting to code and structure means you've already moved up to the next level. These days, I find myself doing more "vibe coding" as a designer in my work, and I feel there is a world of difference between doing vibe coding while knowing the design system versus doing it without that knowledge from a product designer's perspective. I hope you finish the course well, and I will continue to root for your growth as a designer. 🙏
