Do you skip ahead in a book? Do you feel badly about it when you do?
I have skipped some pages in some of the books I read, due to several reasons but mostly because of its lousy plot and never-ending boring descriptions. And no, I never feel bad about it when I have to do it. If I feel that the book isn't worthy of my time, I wouldn't hesitate to not finish it either. The bottom line is, if an author doesn't care about writing a great story for his/her potential readers, I wouldn't be bothered to read his/her books too. The rule is simple.
