I think I'm on track -- but maybe I'm not.

I won't read 100 books by the end of the year, but I'll be happy with 60 or 65 (and I think I'm on track for that.)
I knew that I would only get that far at the beginning, but I put 100 out there because that is what the challenge was and it was a nice round number. Besides, if I surpassed it, then where would I be in December?
