I never used to do this either. But life is short, time is precious, TBR pile keeps growing, etc., etc....as many have said. There was one in particular (I won't mention the title, but it's a Newberry Honor book) that I could not make myself finish. And one that I'm reading right now is a National Book Award Winner, but I'm four chapters in and nothing has grabbed me or enticed me to turn another page. With these two, I think maybe they're just not my cup of tea, seeing as how they've been so well received by many others. But no, I won't keep reading a book just to see if I'm pleasantly surprised in the end.
