I can really feel that you are trying to teach it to beginners as much as possible. Thanks to you, I was able to realize that I was a beginner even more than that beginner, and honestly, it was hard to follow and it didn't stick in my head after watching it once, so since you gave me a free lecture, I will watch it several times to get used to it. Thank you! I will learn it quickly and move on to the next step.
