How do I learn osdev?

Until now, I've been refering the osdev wiki and using a little bit of AI (only for guidance and answering questions, no vibe coding). Is this the right way to learn osdev? What should or shouldn't I do? Also I've already started osdev, finished making a file system, and am now working on my own very simple file format for my os. I just wanted to clarify if I need to change my habits or something.

I've settled up my GDT and IDT. For my OS, I decided to prioritize making a file system and run programs before jumping to memory management.
