I personally do not do it and if I do it, I ask myself why?

Last time I was doing that was from the Dexter books and I was becoming more and more pissed with the book because I was skipping too much. So I stopped and asked my partner to give me a summary instead.

If half the book is skipped, maybe just search for a summary? It could be the writing style of the author is not for you. Or your brain needs something different (lighter/heavier) at the moment.

I tend to have different books in my Currently Reading so I can switch my attention and keep my brain interested, and if I see one is not interesting I simply remove it. I think we have enough books in our “to read” lists that we shouldn’t really feel bad about removing some for not liking them.
