No.
I don't quite understand what completing 'one of my stories in my lifetime' would mean?
I regularly complete two to three stories a year for my own sales as e-books and paperbacks, and over the last 23 years as a freelance writer, I've sold completed stories in the hundreds to regular clients and buyers .
The novel series that I have ongoing here on Tapas are completed ones being serialized as short episodes for the site's requirement.
For the main comic 'Delphine and Zigadias', the script is complete, and also plotted out in detail. I just need to do the art whenever my work schedule permits these days.
