Going through a similar journey in my life a few years ago, I have been trying to put pen to paper and I'm having a hard time not jumping around a lot in my writing. Did you jump around a lot while writing "Eat, Pray, Love" or did it come out fluid?
Dear One — Who are you writing your book TO? Do you have an imaginary reader? A single person? If not, then you are probably lost in the narrative. I never begin writing a book unless I know exactly whom I am speaking TO. Each one of my books was written to a different person in my life — and I write the book as though I am telling that person a story. So choose someone. Someone you love, ideally. Then sit down and tell the story to that person.
