A while ago, one of my teachers asked what kind of books I like reading. He seemed shocked when I said that I like reading pretty much anything. In hindsight, this wasn't strictly true: there are lots of books that I probably wouldn't read, but was surprised by his reaction. He went on for a while about how our lives are so short in comparison to the amount of books out there, and we should be picky about what we read so that we only experience the best.
I'm not really sure what I feel about that. I mean, while I want to make the best of my limited time on Earth, every now and then, I want to read books that are just good fun, and while not completely empty, are not too heavy or meaningful. What does everyone else think? Should we limit ourselves to what has been deemed good literature? Of course, if everyone did that, no new books would ever be read. Are frivolous books harmful, or do we need to read some in order to both appreciate and rest from more serious literature?
