I'm always enjoying watching this! When I knew nothing at all, I forced myself to push through the curriculum and study, and now it's been a year since I became a junior developer. After a year has passed, I'm listening to the lectures again with the mindset of starting from the basics, and I can see different things than before, and even at work I get that "ah, so that's why" feeling. For those who aren't familiar with this yet, and those who are just starting their careers, even if it's difficult and you don't understand, just keep listening. There's a saying that even a dog at a village school can recite poetry after three years. Don't try to understand everything from the beginning - if you keep listening, you'll become familiar with it, and as you become familiar, there will come a time when it feels easy!! Fighting to everyone.
