This week, BTT asks a question that made me stop and think a bit: "All other thing being equal, would you rather read a book that’s hard/challenging/rewarding or light/enjoyable/easy?"
This one is a little hard to answer (and I'm not sure exactly what we mean by "all other things being equal" -- what things?), because I think I like both those choices. At different times and for different purposes, but I wouldn't rule either of them out. Of course one person's hard/challenging/rewarding might be the next person's piece of fluff. And, speaking realistically, if a book is really so hard to read that it takes a lot of work to get through, I'm very unlikely to stick with it. Which is why Tolstoy, Proust, and David Foster Wallace aren't on my must-read list at the moment.
My preferred reading, of course, would be something that's challenging and enjoyable. Is that too much to ask?
