The personal productivity blog Lifehack.org has published some tips for squeezing more reading into a year, Literary Gluttony. It starts with a list of why one might want to read more, including "knowledge", "keeping your mind sharp", and, interestingly, "pride".
The tips for reading more are mostly sensible, although I would argue about "speed reading" as a first thing to do. I also doubt that any but the most committed of readers will be following the author's lead by getting up at 5:30 to squeeze in reading time before work.
Nothing on the list will be too surprising to a librarian or regular reader, but this looks like a good list for those people who feel that they should read more, but want some tips for how to fit it in.
