In 2021, while I was in a state of burnout, I listened to the JPA/Spring basics lecture and forgot the first part of the content and listened to it again, and as I forgot and listened to it again, I felt the need for SQL, so I studied SQL and reviewed Java, and before I knew it, I was taking the Spring Data JPA lecture. I overcame the burnout well and am now looking forward to the last curriculum, QueryDSL. I really struggled to understand JPA before studying SQL, Java, DSL, and Data JPA, and I took the lecture with my mouth wide open when I saw the convenience features provided in the back as much as I struggled while reading the beginning N times. Above all, in the past, there were many parts that I didn't understand when I looked at the official documentation, but after listening to the lecture, I was so happy that I could say, "Oh, this is the content." Thank you so much for creating such a great lecture. I still feel pressured because there are so many things to study in addition to Spring, but unlike when I was young, these days there are many people who help me like a teacher so that I can study easily. I wonder if I can do it, but I get a lot of strength from seeing myself understanding while listening to the lecture. I plan to do a project after finishing QueryDSL, and I will think about the practical advice the teacher gave me and apply it. Thank you!!
