I seem to be making the same mistake I've been making for quite some time now, in that after I finish one book, I don't seem to start the next book for a week or two. The good news is I have started #76, A House for Mr. Biswas, but the bad news is I didn't start it until yesterday.
I'm not really sure of the reason for doing this, but I think the problem might be that there are currently 199 books on my "to-read" list, and only 25 of them are from the list. Add to that, I have 17 non-fiction books out from the library right now, and they're all screaming to be read!
After finishing a list read, I think my mind set is that I'll just whip through one of these non-fiction books, and then start my next list read. Of course I never read as fast as I think I'm going to, and before I know it, a week has passed.
The culprit this time, since I finished White Teeth, was Walls: Travels Along the Barricades by a Calgarian author, Marcello Di Cintio. He travels the world, visiting different places where walls have divided a society or city or culture. It was kind of a combination political essay and travelogue; basically it was right up my alley.
But that book is finished, so I have moved on to #76. I just really need to make sure I go back to reading two books at the same time; one list read and one non-fiction read. When I have done this, it's really worked well, and I seem to get a lot more reading done.
