I can relate. The thing is, that these "Heureka" moments stem usually from long times of frustration working within a certain domain or with a certain concept.

After working with certain stuff for long periods I can find usually a way to explain it in a very easy way. However, this does not mean, that concepts are easy to grasp without putting in more time and learning all about what my abstraction kept out.

It is still a hermeneutic circle.
