It's fairly similar from what I've observed myself, but I'd say the ah-hah! moment for a given subject is not a singular event, but can be repeated if you look at the same subject from a different angle and get a different insight, deeper understanding of the solution or even of the problem. But maybe that's because learning in my case often is very much intertwined with trying to solve a problem.

And there's:

-1. Come across the solution by talking to people, reading books, articles, videos... long before actually needing it, sometimes not even being able to recall it in the next steps until the ah-hah! moment.

0. Have an actual need for that solution due to a problem you're trying to solve. And having that feeling of "there is a solution for this" but not being able to put your finger on it.

Talking to people helps a lot to speed up the process because everyone will have their own view on things which helps to shape your own understanding of the subject.
