There's a lot of research on the efficient acquisition of skills. Especially problem identification and solving.
One key part you might be missing is "rule generation". It's the ability for you to abstract the fundamental rules of what you learn and apply them to as many problems as it can be applied to. For example upon learning the solution to differentiating x^2, a person might have such a terrible ability to generate rules he only learns how to differentiate x^2. But someone with a tremendous ability to grasp the fundamental logic of differentiation, of the rate of change between two infinitely small changes, could from seeing the solution to differentiate x^2 could apply it to find the rate of change of the decrease in height of water in a cone as a fixed amount of water is drained from it. Von Neumann reportedly had this tremendous ability, an ability to grasp the "superstructure" of a field of mathematics he had never learned prior and conduct research into it.
