Hello, Gwiyeomdungi. Thank you sincerely for taking the course and for the detailed review you left. I am very happy that the lecture seems to have been helpful for your learning. Spring Boot can feel a bit difficult for those encountering it for the first time. Also, if there isn't enough lecture time or if basic concepts aren't properly organized, many people find it very difficult to learn. I tried my best to explain things as easily as possible, and I feel a great sense of reward knowing that the lecture helped fill in the gaps you had, Gwiyeomdungi. It's especially impressive and wonderful that you took the time to study despite it being a holiday period. I believe this kind of consistent attitude is ultimately the greatest driving force for improving skills. As you already know, I'd like to add some points that might be helpful for your studies. Even if you encounter parts you don't fully understand while studying or developing, repeating the process of creating projects yourself and resolving errors will gradually lead to understanding and familiarity. It's important to build a solid foundation in basic concepts (e.g., dependency injection, controller-service-repository structure, REST API design, etc.). And more than anything, the 'experience of creating something yourself, no matter how small,' helps you grow your skills quickly. I believe your current efforts will surely become a great asset later on. If you keep moving forward step by step, you will definitely become a great developer. I sincerely support your future growth and journey as a developer. I will repay you with even better lectures. Thank you!
