The main thing is not to bother with a bunch of materials, but to choose one thing. For example, when I studied unity, I gathered a lot of different resources, services and courses. In the end, I was torn between all this. Then I just focused on one of the courses and the process started moving. I advise you to choose the method that suits you the most and only deal with it, then you can change it. The main thing is not to spray your attention.
