How Robert Caro starts to write a book:
"I can’t start writing a book until I’ve thought it through and can see it whole in my mind. So before I start writing, I boil the book down to three paragraphs, or two or one—that’s when it comes into view. That process might take weeks. And then I turn those paragraphs into an outline of the whole book. That’s what you see up here on my wall now—twenty-seven typewritten pages. That’s the fifth volume. Then, with the whole book in mind, I go chapter by chapter. I sit down at the typewriter and type an outline of that chapter, let’s say if it’s a long chapter, seven pages—it’s really the chapter in brief, without any of the supporting evidence. Then, each chapter gets a notebook, which I fill with all the materials I want to use—quotations and facts pulled from all of the research I’ve done."
