PQ has a nice piece up "On the Allure of Reading" and the difficulty of getting to everything that he wants to read. I totally relate -- I have started listening to audiobooks on my commute to work more often because it increases the total number of books I am able to consume.
When I got out of college, more than 30 years ago, I was swept with an enormous feeling of relief, because I could choose which books I wanted to read in my spare time, as opposed to having to read the books my college professors wanted me to read.
Each time I choose which book to read next, I have to decide between a book that relates to this blog and one that has no connection. There's always a little bit of guilt when I'm not doing my "homework."
