So … you’re halfway through a book and you’re hating it. It’s boring. It’s trite. It’s badly written.Sometimes I finish, sometimes I dump.
But … you’ve invested all this time to reading the first half. What do you do? Read the second half?
Just to finish out the story? Find out what happens? Or, cut your losses and dump the second half?
It depends a bit on "why" I'm reading it.
If it is a book I have heard other people discuss, and I'm reading it to be able to join the discussion, I probably try to finish it, and analyze what it is I don't like about it. But if it is a book I happened to pick up more randomly, I probably just dump it. I might also just page through the rest of it really quickly and have a peek at the end!
If it is a well-known classic, I might try and find a summary or review to help me understand what it is I'm "supposed" to see in it. I have a few books on my shelves that I only got halfway through. It happens that I lay one aside for a while for something else. Sometimes the time and circumstances in which you read something matters, too. It happens that I try an abandoned book again at another time, and like it better than I did the first time.
