There have been so many books that sound good but when I start listening (I do audiobooks), I just can't get into them. I push myself not to throw in the towel too soon but I never know what too soon is. I often hear "stick with it" or "it'll make sense in the end" and lately I have found that I've pushed through and not enjoyed the book at all. Do you have a hard and fast rule about when you DNF? Or how do you make that call? On the one hand, I don't want to spend my time with something I don't enjoy and on the other, I hate to think I wasted the time that I did spend with it if I don't finish it. (I'm very bad with all or nothing mentality sometimes.)
