In 2007, J.K. Rowling finished writing the seventh volume of her seven Harry Potter books, Harry Potter and the Deathly Hallows. It sold 11 million copies its first day out. Rowling had written the final chapter of this last book way back in 1990, when she first conceived the story she spent the next 17 years writing. She knew the end right from the beginning. There’s a similar theme unfolding in the weeks ahead. As you plot a project you’ll develop for a long time, you envision what it will be when it’s done.
