Writer's Practices

Well it turns out my sister is actually in the process of writing a book. If you're so inclined, you might get to read it :) Anyway, when I ask her what she does when she is about to write some of her book, she gives me a very odd answer. She tells me that she thinks about what she is going to write by thinking of something else. I guess its kind of like letting life write the book, or more so that it will be more realistic if she can take something from her life and make that an element of her writing. Its almost like Archimedes's Eurekas syndrome. That is the concept that if you cannot solve a puzzle, the answer will come to you as you engage in an activity that is not related to the puzzle in any way. That practice seems to support the premise that writing has a mind of its own.
