I find no time for many books these days, which is why I have a massive pile of unread books that looked interesting at the time. Fiction or non-fiction, the same. What with TV, radio, Internet, occasional magazine, etc. I just don't find the enthusiasm for them any more. I'm unsure if the changing environment, or whether it's changes in me that caused it. When I used to read books more, I rarely didn't finish them. I can only think of two where, when I put it down I found it impossible to pick up again. Although perhaps there were more I've forgotten.
