I've got a good 5 weeks left in which I can do some serious reading. There are so many books I want to read before then. My problem is I waste so much time trying to get into books that just aren't sucking me in. I need to come up with a plan as to when I declare a book a dnf-er.  I'm thinking two days or 100 pages. Sometimes I know that I can't get into a book because my mind isn't ready for it, etc. So maybe if I put the book down read something else and then revisit it and it still isn't capturing me, then I'll label it a dnf-er?  What do you guys do about dnf-ers?
