I used to think so about books... but after some thought... why?

If you still read enough articles/books/whatever (so it's not your attention span failing), and if the article/book wasn't "good enough" to keep you reading it, why does it matter if you didn't finish it? There are many more articles and books than you are able to read, keep with the 'good ones' and forget about the rest.
