I must admit I once felt I had to finish every book I started. But I have since adopted this eminently sensible suggestion: read the first 50 pages of a book to give it a fair chance, and if you're not enjoying it by then, give it up. There are too many wonderful books in this world to get stuck with one that doesn't satisfy. If you've been trying to get the same book read for months now, that's probably a good sign it's time to move on. Give yourself permission to read only what you love - reading is such a joy when you find the right book!
