I don't have any side goals/challenges and so far I've read 26 books this year. Goodreads says I'm 11 books ahead of schedule, which I think is okay since last year I had a couple of months where I was 8 or 9 books behind schedule.
I'm reading a lot of shorter books because the longer book I would normally read is not one I'm excited about, so I switch to the shorter books that I normally only read at times when I'm less focused. (It's not a bad book; it's a compilation of short stories and I just find I'd rather continue a longer light-reading book than plod through a short story.
) I expect my book completion will slow down to a more normal pace when I finish this collection and return to my "regular" reading.
