Hello Younghan. First, cutting to the chase, thank you so much for creating the Java roadmap course. I'm a junior developer who started with government-funded training and became a 3rd-year developer last year. Although I had been working continuously in practice, I felt the limits of my growth and quit my job, then enrolled in Younghan's Java course roadmap. Through Younghan's lectures, I deeply learned about things I had been curious about, things I had used without understanding simply because I was told "just use it this way" - how and why they came to exist, and how they can be utilized. I briefly wondered if it was right to take the course before starting the practical Java roadmap, but it was such a meaningful course that the time I spent worrying about it felt wasteful. When I look back at the end of this year and think about what I did best, completing Younghan's Java roadmap will probably be the first thing that comes to mind. I remember what Younghan often said: "It's laborious for those who make it, but convenient for those who use it." As much as Younghan works hard, I am building my Java fundamentals comfortably and solidly. Thank you!
