I experienced an identical problem a number of years ago (8), when I stumbled onto a great idea for a historical fiction, that got a lot of attention from potential publishers, and even a film-maker who expressed interest in making a film out of my book when I finished it. My only problem was — I had no established writing routine at the time.

I had created such expectations that I couldn’t possibly meet, I brought on a writer’s block so bad, I couldn’t even journal for about 6 months, so convinced I became that I was no writer and had fooled myself and the world into believing that I was.

Then I found a place called Cowbird (long before I found Medium), an online storytelling platform, and the writing floodgates opened up. I found a writing discipline like I’d never had before, writing two — three hours daily, and learning to make it a priority in my life.

I’ve never made it back to that book, but I’ve written the equivalent of 7 or 8 other books, that now just require the discipline of serious editing and rewriting that I have also learned how to do, and will apply to all that already written raw material when I retire from my “day job”, in a year or five (hopefully closer to a year). I learned that the discipline that will take, I don’t have the time for while still working full-time, but will be a perfect retirement project.
