I had quite a similar experience. During the 3rd attempt at learning, everything seemed to click and I was able to be effective at writing a few programs.

This is all despite a long career as a programmer. Seems like some things just take repetition.

The "Dagger" dependency injection framework for the JVM took me 3 'learning attempts' to understand as well. May say more about myself than about learning something somewhat complicated.
