This is a lecture that I really don't regret spending money on. I've taken many online lectures, but this is the first time I've taken a lecture that was this enjoyable and fun! I'm sure you're busy with your main job, but thank you so much for preparing such a great lecture. I found it by chance, but whenever I watched the instructor's recorded screen, it seemed like the clock was mostly late at night... Despite that, each lecture seemed to be prepared with so much passion that I ended up paying more attention to it! Also, I could see that the instructor was full of love for programming in the lecture, so it was a lecture that I enjoyed listening to even though it was difficult. I learned a lot, not just from the Spring lecture! Thank you again!!
