Now you have all the material you'll need to write a story or book. Don't be too eager to write it, though. You shouldn't write a whole book or story in one day. Quality should go before quantity. If you write too much, your attention will fade, which doesn't help your story in a positive way at all. Furthermore, you might get bored if you spend to much time with your story. If you stop writing only when you are stuck, it will be very difficult to pick it up again. It might be best to stop writing when you still know what comes next.
