When I turned 40 I figured my odds of living another 40 years were pretty good. I then figured that if I continued to read one book a week (my average) for the rest of my life, I would read another 2,080 books. That sounds like a lot but really it isn't, especially when one considers how many great books there are out there that one hasn't read. Many more than 2,080! So now when I consider reading another book I ask myself if it looks good enough to be one of my 2,080. Many books do not make that cut. I think it's been a good filter and I expect as I grow older, and I have fewer and fewer books looks left to read, I will get even more selective in what I read.
