So … you’ve just finished reading a book. For the sake of the discussion, we’ll say it was everything a book should be—engaging, entertaining, interesting, thought-provoking. The kind you want to gush over. The question is—do you immediately move on to your next book? Or do you take time to contemplate this writerly masterpiece and all its associated thoughts/emotions/ideas for a while first?
Usually I move on to the next book, since I read more than one book at the same time but I almost always have a few days to contemplate when writing the review while the book is still fresh in my mind and the details are strong. :)
Occasionally though, I would start a really short story (less than 100 pages) while writing the review (and abandon it, come back to it later, tearing it apart virtually and rewriting it again. Repeat cycle) until it's not fragmented and sloppy like my notes at school. But with my happy-go-crazy schedule and my "pretty slow" reading skills (I can read fast if I choose to... but words just fly over my head and I have to reread again. Better read slow and know what you're talking about than read fast and have no clue at all. Of course... that's only in my case.), as soon as I finish one book, I have to start the next book ASAP.
But what if I don't have a short story? I would take one day off from reading the next book to ponder on my thoughts and emotions while tackling the review. (Minus school if it hits study days because I have to work anyways or get in trouble, so... that's an exception.)
In the most part though, I generally have to start the next book immediately.
