If a book gives you one extra idea, one extra concept or one not obvious link between concepts or ideas that you already have it worths a lot to loose time reading it. If you read 500 books like this you get much more intelectual rich than a non reader person. I can regret a lot of stuff in my life but I don't regret reading most of the books I have read.
