Yes. Many times I found the actual problem is something slightly different and often simpler than what people think. It's a kind of superpower to think this way.
Exactly, it's a bit unbelievable when you consider that the symbology has some unnecessary abstraction.
But yes, it's really great to then discover that it's almost elementary, so to speak. It's something that stays with you for the "next" challenge, knowing that at some point it will loosen up and the basic form will become visible.
