Okay, so I did some research about my "when to quit" dilemma.
Answers were all over the board. Some people said that as soon as you start questioning why you're reading the book, it's okay to decide not to continue. Others said you needed to give it a certain number of chapters, or a certain number of pages.
And of course, there were the diehards who said you had to finish, no matter what. Some of my most admired reading friends fell into that category, and I was mildly ashamed of myself for even asking the question, given their stalwart sense of what was necessary . . . even when they very kindly said they wouldn't think less of me if I didn't hold myself to the same high standard.
I had fun researching the question and soliciting opinions. In the process I realized I'd probably never get over my disappointment if I didn't stick to my personal goal.
It's the goals we set for ourselves that are the hardest to abandon, am I right?
So. Onward! I said I would read all the Booker winners, and I will. Because no one can give me permission to abandon a self-imposed goal except myself, and I'm not going to do that.
Besides, the book has picked up a little bit lately. I think I'm actually beginning to enjoy it.
