There has been some good material posted recently on reading.
Gretchen Rubin of The Happiness Project provided Twelve Tips For More Reading. She share my view that you need to quit reading if something is not working and move on. "There are too many wonderful books to read."
Michael Hyatt posted his How To Read a Non-Fiction Book a few weeks ago. He takes notes in the margins, has a set of symbols for note taking, and dog-ears pages he wants to return to.
Brian Oates at daxle.net says you should jog, walk, and then stroll through a book. "Non-fiction is about learning and can be tackled differently. You should read a non-fiction book on purpose. The more clear you are on why you are reading it and what you want to learn the better."
And if you are really serious, pick up a copy of How to Read a Book by Mortimer Adler and Charles Van Doren. Here is what they authors say about reading practical titles like business books:
The most important thing to remember about any practical book is that it can never solve the practical problems with which it is concerned. A theoretical book can solve its own problems. But a practical problem can only be solved by action itself. When your practical problem is how to earn a living, a book on how to make friends and influence people cannot solve it, though it may suggest things to do. Nothing short of the doing solves the problem. It is solved only by earning a living. (p193)
I borrowed the title for my ChangeThis essay from Alder and the opening story has me making fun of a kid who is walking around with a copy of the book. Just for the record: I was wrong and would recommend How to Read a Book to anyone who is serious about getting more out of what they read.
