Every time I watch the lecture, I feel like, wow, this lecture is really the best! Can there be another lecture like this? Like magic, Younghan's lectures always give me the impression that they are the best. This lecture was also the best lecture. In fact, it's been a long time since I paid for the lecture, but at that time, I was attending SI and had just started studying, so there were a lot of parts that I didn't understand. So I held it for a while, and then after about 6 months, I brushed up on the basics and watched the lecture again, and I could feel that it was a lecture that was really a new world. In addition, there was a part where I was applying AOP as if it was a lie and called an internal method, and AOP had to be applied to the internal method as well, but if it weren't for this lecture, I would have struggled for a long time. However, thanks to the lecture, I changed the part that Akina logic didn't change much among the three alternatives given, and it worked really well. I am always grateful. I paid for all the lectures and finally listened to them all.. I know it will take a long time for Younghan to prepare the next lecture, but I really want to watch the new lecture tomorrow.. I am always grateful. I hope you take care of your health in this hot weather. Thank you so much ^^
