Or like consumptive knowledge vs. participatory knowledge or something.
I notice a huge difference between things that I consume alot of content for but don't engage with, vs. things where I actually try to apply the knowledge. Your brain makes connections in a totally different way when you try to apply the knowledge.
I watched piano tutorials for like a year before I finally saved up for a decent digital piano to play at home. I had tons of little facts and ideas rattling around my head, which were actually very helpful, but completely disorganized. Every time I learned a new piece, some of that loose knowledge would Tetris into place, and things would get a little more coherent.
But there's always this gap between my pool of ingested information and my ability to do something with it.
