I took the two roadmaps and they were really helpful. It's the best lecture that makes me wonder if I could become a backend developer without Younghan's lecture. I still have a lot of shortcomings and need to study repeatedly, but I'm trying to acquire all the contents of the lecture as my own. At one point, I was really proud to see that I was speaking like Younghan. While studying at the boot camp, it felt like I was building a building on sand, but while watching Younghan's lecture, I can feel the sand turning into solid concrete. Sometimes, the lecture is so good that I wake up in my dreams, and I'm thinking, "Wow, I also work hard and dream of working with the best developer like Younghan." I'm hesitant because I don't have much to say, but the lecture is really great.
