I saved it and couldn't watch it because I was doing other things, but now that I'm finally taking it out to watch, there are shocking realizations hidden in it. I'm currently doing native speaker video English lessons after paying nearly 4 million won at once, but I'm having belated thoughts that if I had watched this video first, I might not have spent money on English. I should finish watching it completely and apply it directly to real situations. I have weekly meetings with overseas developers, and I've gained confidence that I won't get English anxiety anymore!
