At some point you need to stop reading and start executing. But, don’t feel bad about reading if you still haven’t filled you tank.
For books? Come on... Just dedicate some quality time daily and choose a book wisely.
Speed reading does work well, but you have to deliberately practice comprehension. I've read well over a million words in the last month. Fiction and history books are especially wordy, but are worth reading fast. Ever read Stephen King? He's got some excellent ideas, but you have to just slog through the descriptions. I'm grateful I can speed read as it makes the book more like a story that flows.
But in general, the really good books are very hard to read, because the ideas are hard to grasp. Going for X books a year means you end up selecting "easy" (and thus, less impactful) books.
This has the same problem as "going to college won't get you a high paying job".
I'd probably benefit from reading fewer books, but sticking with quality material.
I wouldn’t be surprised if most people reading at this pace have a library similar to barnes and noble, with perhaps the cult classics of their field. But I can’t imagine their actually committing to much research in each subject area, and thus, not much depth
I think this falls into an optimization fallacy, where you are trying to optimize for some faraway conclusion like success and miss the forest for the trees. Reading, even a fun novel, is very beneficial.
My point is that both quality and quantity are important (and diminishing returns apply). The speedreaders described in the article Im assuming have focused primarily on quantity, leading to the lack of value derived.
