I always thought the way I read items that weren’t very interesting was cheating… but apparently it’s called speed reading. Kim Roach wrote a spot on ZenHabits about speed reading, and it’s rather great. It talks a bit about how to drop the inner-monologue, in attempt to soak as much information as possible. She introduces Spreeder, which helps focus your speed reading ability. If you’re reading an article, copy/paste it into Spreeder and practice.
By simply learning how to process information at a more rapid rate, you’re not only going to be able to move through books more quickly, but you will also be able to comprehend and process more of what you have read.
