Hello, Professor. I finished this lecture as well. I followed the roadmap for about a year, listening to lectures after work and on weekends, but now only the last chapter of the grand finale is left. I am so grateful that you always explain the background of the technology and why it is used so that anyone can understand it, and try to convey at least one more thing. Sometimes I see the professor's computer time while watching the lecture. Sometimes it is a number, and sometimes it is a clock shape, so I thought that he was hiding it on purpose. Hahaha. Anyway, watching you film lectures at various times from early evening to dawn, I often reflected on myself, thinking, "The professor is filming such great lectures so diligently, but am I working that hard?" You provided such great lectures and gave me generous advice as a senior developer, so it was a year of time where I was able to gain motivation not only for technical learning but also for life. I think I will be able to maintain this system well and develop happily in the future. Thank you.
