The thing is, this method cannot teach me anything that I don't need immediately. I can no longer ignore this. I feel it's time to start learning basic topics, or should I say, fundamental computer science theories that are taught in textbooks in university classes, so to speak.

By using the pragmatic approach that pushes back advanced topics and only tackles beginner-friendly problems, I can grasp the big picture of programming. Making a fully working application can teach me a lot more than focusing on details.

I've never learned computer science before, I just learn through the experience of programming. By doing so, I have nothing but the techniques and methods that come from experience. This was OK at first, it worked very well when I started programming as a beginner.
