I feel this way in JPA lectures and other lectures, but I really like how the lecture introduction always starts with a bright and energetic [Hello] and explains the direction of the lecture. I don't know why, but whenever I watch the lecture introduction, I feel excited and nervous like when I first learned programming in college. I think it's because the lectures are so good that I unconsciously feel excited and anticipate what new content I will learn today. That's how great the lectures are. I look forward to future lectures. Thank you for the great lectures.
