It felt different from the lectures I've seen so far, and I felt like I was taking a break, so I took the class comfortably. It doesn't mean that the lectures were light or easy. In the past, I liked the lectures that crammed in a lot of knowledge and skills(?) (I felt like I was getting my money's worth😁), but sometimes it was hard to keep up, and I was confused whether the lectures were for the students or if the lecturers were just displaying what they knew like trophies and building up their own achievements. Eunjae's lectures seemed to have a good balance. They were moderately wide and moderately deep. Above all, it was good because I could experience following the flow of thought as if I was solving a problem, rather than memorizing formulas. It also gave me a chance to think again about things I didn't know, but just took for granted and didn't wonder about, and things I didn't care about because I considered them unimportant. I need to look back on how I deal with and think about problems, and what kind of attitude I've had so far. If you have the chance, it would be great if you could share Eunjae's tips as a developer (what tools you use, how you work/collaborate, etc.). I look forward to seeing you again with another great lecture. Thank you.
