Writing is a process, not an event. Children trained in the process of writing learn to view the final draft as merely one of several steps in an evolving work. And when the steps seem doable, even the most intimidated writer stands a chance at accomplishment.That paragraph sums up this whole book for me. Writing is a process, it has steps in it, and one needs to learn those steps in order to write decently.
The author goes on to speak about different things we can do to encourage or help the struggling writer. From brainstorming, to provide concrete ideas to start with, and so forth. But the biggest thing we can teach our children when they are learning to write is... one step at a time leads to a finished product.
