A good book can give you a new way to interpret your past experiences, but only if you can internalize the insights from the books you read. 7 methods on how can this be done more effectively:
Skim the table of contents, chapter titles, and subheadings. Within ten minutes, you will have a reasonable idea of how good it is. If it is not for you, quit it.
Choose a book you can immediately apply so you can stay motivated while reading it.
Create notes for your book, and make sure they are searchable (i.e. Evernote).
The trunk of the trees will contain fundamental concepts, and the branches form the details. Do this for each book and "link branches" to integrate your current book with other knowledge trees.
The Feynman Technique: write down how you would explain the book to someone who had never heard of it.
If your life revolves around the ideas of one book, they are likely unsound. Read a variety of books on the same topic.
Doing this will help you catch ideas that you missed the first time around.
