It was easy to understand and good. The explanation was really good, and the visuals? were really good too. If I had listened to this at the beginning of my development studies, I think I would have been a better person than I am now. Of course, I think my future self who listened to this would be very smart. I listened at high speed because I already knew the first part, but the pronunciation was good, so I could hear it even at high speed. And as I listened, I realized that even though I was studying, there were a lot of parts that I didn't know... I was a little overconfident, but this was an opportunity for me to come out! Thank you.
