A long time ago, and as a form of self-imposed discipline, I decided to keep a list of the books I started to read, followed by a list of those I finished. We’re talking 1980 here (before there was a thing called Internet as we know it today). Unfortunately, and despite all this information, I don’t have the faintest idea how many books I read since 1980. I have notebooks, one for fiction and one for non-fiction in which I keep my lists and mark each book out of 10 - I haven’t read anywhere near the number of books I should have since we are talking many eons here, but I find it helps me remember books and spurs me to complete some I would otherwise give up on.
