One writer's process
Everyone has their own process. What works for you is a disaster for me. My way bores you to death.
My process is layered. I try to have a big picture and layers of detail. My background is software development and I am used to running projects with tasks, milestones, all visualized in Gant Charts. ProjectLibre (free open source, similar to Microsoft Project) is a nice tool for me. I have the next year laid out in it. I'll be concentrating on Novel 2 from now until 1 Jan 19, back to Novel 1, which is currently out to beta readers, for a few months, then back to Novel 2. Those big blocks are broken into subtasks with estimated durations, etc. I look at my overall project frequently, updating progress, or lack of progress, adding tasks as I see them crop up. I don't emphasize word counts, but I use them when I think they will help structure the work. My goals are mostly in terms of planning or completing scenes, verifying timelines, identifying and implementing subplots, etc.
In addition to the ProjectLibre, I was indoctrinated for years into a corporate "Balanced Scorecard" view of life. For me, in this phase of my life, my balanced scorecard is divided into 4 areas, like a traditional business balanced scorecard, but my areas are: Life, Writing, Platform, and Education. Every day, I lay out goals for myself in each of these areas. My ProjectLibre plan is background long term guidance. Under Life, I might plan to vacuum the living room, read Meister Eckhart, lift weights, music practice, work in my wood shop, and shop for groceries. Under Writing, I might write 2000 words on a scene or chapter, edit a chapter, or read a chapter or two aloud. Under Platform, I might research markets, post to Facebook, write a blog, or prepare for a class I am teaching. Under Education, I might read a book on Blockchain, Aristotle on Poetics, Ursula LeGuin on Steering the Craft, or Jane Friedman on the writing business.
First thing after coffee each morning, which usually starts at 5a for this farm boy, earlier if I can't sleep, I look over my scorecards for the last few days, checking off what is complete, on going, rightly neglected, or in need of attention. (The Life section always has the most neglect.) Then I create a new score card for the day. Each day is a new day and I am flexible. I forward or add goals, some that I know I won't meet, but I want to keep in mind. Often, I abandon goals as events overcome them. I keep this in OneNote. It works for me, but there are hundreds of tools that you could use. Pencil and paper work fine, but I find them messy.
I don't mean that my method will work for everyone, and I am certain that my way of doing it will repulse a lot of people, but if you are looking for a way to organize your creative life, these are some ideas to consider.
