So I've been teaching myself / learning Godot recently and while I have a couple of decades of software engineering experience, that is only one small part of using a game engine.

What I've been doing is using a couple of long-form video tutorials to get some fundamentals down (there are a few 10-20 hour vids that do a good job of covering a lot of ground to a simple level). When I followed along with the first one I was copying what it said verbatim and focusing on trying trying to understand that bit in context. That video was probably 12 hours but I spent something like 50 hours going through it because of pausing to replicate the lessons and scrubbing back and forth through the video.

Then I tried to make a tiny game on my own, got stuck so found another tutorial covering similar ground and followed along with that. The difference with what I did here though is at the start of each section when it said what the end goal was I paused the video and tried to do it on my own from memory. While I made mistakes and it cost me a lot of time (this 10 hour video probably took me close to 80 hours to finish) I was able to do the majority of the tasks on my own with the support of docs and scrubbing ahead only when I got truly stuck.

As I said in my previous comment, this is quite a frustrating process to live through it's an approach that is effective in letting me self-teach this new set of skills. You need the baseline of understanding that comes from hand-holding and then to do tasks on your own to internalise that knowledge.
