It was so intense that it was among the top 3 most useful videos I have ever heard. I will definitely watch the videos that Zombie makes on Inflearn in the future. In particular, I would like to see a video that shows how to make an app from start to finish, using a server and development tools, such as a diary app or a weather forecast app, and that allows you to check the code (even if the video is short, I would be very happy. Loyal customers are always sincere. Also, as Zombie said, failure is always a necessary process, and I don't think it's possible to make something perfect from the beginning, but even so, loyal customers are sincere just by making a video, taking failure into account.) Or, if you make a video of a project that starts with nothing and makes about 100,000 won by observing it from start to finish, like the popular "Surviving on Nothing," even people who don't know what to do will be inspired just by watching the video and following it. In the past, one of my friends didn't know how to use a PC room at all, but when I took him there and showed him in detail, he started spending all his days off at the PC room. And after that, when I saw my friend sharing the tips I didn't know about, I realized that it's important to make even the smallest things specific.
