As a developer who has some practical experience, I was able to 'understand' the lecture content at once. So when I felt a little bored, I let out a silent scream in my head, 'Oh..!' I realized that the lecture content was the reason for the incomprehensible codes, functions, and designs I had experienced before. Next, you said, 'I don't want to be just an average developer.' Through this lecture, I think I have gained the strength to think about the parts I didn't understand and just passed over in the past. I think I will be able to become a developer who thinks more deeply to grow in the future, and I am grateful for giving me the foundation for that.
