Sorry for all you folks who had the 'ah ha!' moment many ears ago and you got to listen to my drooling ;)
Drool right ahead, I think most of us continue to have those 'aha' moments that are new to us but others have known for ages.
It always strikes me like "Now I know what they've been talking about all this time!".
I think that's all part of the fascination of the subject there's so many new things to be discovered along the way and each time it brings new insights and ways of working into play.
Enthusiasm is infectious, I'm loving yours...
