Basically, sometimes one may find out too late that a book isn’t quite up to one’s taste. The book might not be gripping enough due to many factors. In such case, would you quit reading it? Does the amount of progress you put in make a difference? Or would you be nontheless determined to complete despite not feeling any meaningful connection?
In Ali Abdaals video on learning from audio books he says that its OK to not finish a book if its of no use to you, or you’ve got all you can out of it. I agree with him read what you enjoy
That’s a healthier mindset now that I think about it.
