Marking a book is literally an expression of your differences or your arguments with the author. It is the highest respect you can pay him.

Reading should be a conversation between you and the author. Assuming you picked up a good book, the author knows more about the subject than you do. Ask him questions to help you understand and argue with him once you've learned what he had to teach you.

Engage with the author

Write in the margins:<ul><li>Questions that come to your mind</li><li>Differences in opinion with the author</li><li>Reactions to what you are reading</li><li>Sentences that summarize long arguments</li></ul>

Marginalia

<ol><li>Summarize and write your unanswered questions at the end of each chapter</li><li>After a week go through your notes and pick the ones you still find interesting. Write them on the first page of the book along with a page number.</li><li>Copy the notes into a digital system for later reference and search. Connect them to ideas you have previously read.</li></ol>

Learning something new as an adult is a function of consuming information (<a dir="ltr" href="https://medium.com/personal-growth/what-you-spend-time-reading-changes-your-brain-ee2ab4f2aa17#.ta4q3fguz" rel="nofollow">what you read </a>and <a dir="ltr" href="https://fs.blog/how-to-read-a-book/">how you read </a>), the information you retain, and your ability to put what you learned into practice (recognize patterns). For this, I use a simple three-step note-taking process that scales up to 150 books a year.
