"The problem with books and all these things is they either are not worth what you pay for them, or worth considerably more."
Comment by "Andrew" at the Marginal Revolution blog.
This is so true. A good book, or movie, or short story is a joy. Some issues of the New Yorker have been worth many dollars to me (especially the ones that had long articles by John McPhee).
But a bad book is a double burden. It wastes your money, and then wastes your time. Even worse is a gift book -- you can end up resenting the giver if you feel you have to read it to satisfy them, not because you really want to read the book.
