I have way too many books that I want to read to keep going with something that I don’t care about. Often if I am getting distracted and having to force myself back to it, I’ll skip 20-50 pages and read a page or two, and that’s often enough to get me to question and want to know how we got there, so I’ll go back and read. If that doesn’t work I may read the last few pages. if my curiousity still isn’t sparked, I’ll often give up at that point. I know I’ve gotten as close to 20 pages to the end of a 500 page book and just didn’t care, so I quit. Life’s too short, and too many books.
