That might sound like an obvious, or even slightly silly, question but it is one that I have been asking myself over the last few weeks. There have been various things recently that have made me ponder this and so I thought I would use the blog as a sound board for them, but also to see if any of you have pondered the same things too.
I used to plough on till the end of every book I chose to read, now I think life is too short and might even give myself up to 100 pages before I give up. I still accidentally find some great books as you suggest and often it's just luck.
