The main idea, able to be generalized, I get from this video is that in order to develop any skill, whether it is learning or something else, you need to break it down into its constituents, much like the 4 Component Instruction Design model argues, and figure out where your weak links are.

The more accurately you know the system of your skill, the better you know what to potentially improve on. This requires research, and sometimes asking experts.

Another benefit of networking.
