First of all, congratulations on completing Younghan's roadmap lecture!! Thank you for always giving great lectures. When I first took the Spring introductory lecture, I think I was hooked on Younghan's lecture without knowing why. (I think it's because Younghan's lecture was that great haha) That feeling grew into the will to complete the roadmap, and eventually led to the completion of this roadmap. As I ran through the vast amount of roadmap, there were parts that I couldn't remember, so I felt that I needed to go through the process of acquiring it as Younghan mentioned in the lecture. I also want to acquire this every day and reach my desired goal! I will continue to wait for Younghan's new lectures in the future :) To all the developers who are reading this course review at the end of the roadmap like me, thank you for your hard work!! I hope you will take each step toward your goal, no matter how long it takes.
