This is generally my approach, not just with books but with TV shows and movies as well. Unless there's a compelling reason for me to forge on, I give something a chance and then abort early if it doesn't show a promising yield.
I also take a version of this with informational books. I read until I feel I got what I needed out of the book, and then don't feel pressure to read on if what's left isn't of interest or need.
