One of the biggest mistakes readers make is assuming that all books should be read from the first page to the last page in an unbroken sequence. For non-fiction books, learning is non-linear. Non-fiction books are for thinking, not reading, and context is king. Break out the highlighter and pen to take notes in the marginalia. Argue with the author. Fiction should be read linearly while non-fiction benefits from non-linear reading. Finally, it’s important to engage with ideas messily and unpredictably, rather than assuming you need to have a rigid note-taking workflow.
