When I was a kid, whenever I was learning about some aspect of computing, I would have a running monologue in my head about how I would explain this to someone else, to the point that I would write out on a piece of paper an explanation of e.g. an adder composed out of boolean gates, or of how 2's complement made negative numbers work, out of sheer enthusiasm for what I was learning.
