I am a resident freelance developer who dreams of becoming a digital nomad. I was at a loss as to where to start in order to become a digital nomad, but I think this will be a good guide for people like me. It is not burdensome to study and is easy to remember because you explain the key points briefly and concisely. I would appreciate it if you could flesh out the content explained in this lecture in the future and create an in-depth course by supplementing the topics not covered in this lecture.
