The rule I like is ‘one hundred pages minus your age.’ Say you’re 30 years old—if a book hasn’t captivated you by page 70, stop reading it. So as you age, you have less time to endure crap.

This post comes perilously close to one of those insufferable LinkedIn “if you’re not reading Marcus Aurelius from a beat-up paperback, are you really reading?” humblebrags, but I liked this rule in particular. The older I get, the more likely I am to DNF if a book isn’t holding me.
