I have too many different topic pages, not one blank page.
So, I drop ideas into word documents in the “Ideas” folder and add things from time to time. When I have thought about something long enough, I start by writing the first paragraph.
I’m sure that everyone has their own process. It’s just important that you have one.
Of course, I don’t write for a living and never have deadlines.
I never write fiction. I am not nearly that creative.
