Perhaps its just that modern writers have been so long divorced from the ideas of classical rhetoric that they're making the process so much harder than it needs to be. Do writers know what they really need in the first place? Perhaps they've been putting the cart before the horse for too long.

Rethinking one's writing process to start at the moment of reading and annotation is possibly a far better method for composition? Then instead of needing to do the work of coming up with an idea and then researching toward one's idea and then creating something de novo, one can delve into one's notes of things they know have previously been of interest to them. By already being of interest or answering questions they've previously asked themselves and had interest in pursuing, they might make the load of work more evenly spread across their lives rather than designing a massive mountain of a problem first and then attempting to scale it after the fact.

By building the mountain from the start, it then isn't a problem to be solved, just a vista from which to stand and survey the area.
