Literary success conjures up visions of going on multi-cities tour, winning the Pulitzer Prize, having one of your books get to the top of the New York Times bestsellers list, and making much money, or at least enough not to need any other source of income. In all likelihood, this is how most people who do not write would define it.
For some writers I’ve known, who wrote literary and esoteric fiction never intended for the masses, literary success is having an appreciative and dedicated following for what would never be mass-market success as in the above.
For others, it means being traditionally published. It's a milestone many try to reach.
I think all of the above qualifies. But I have long held to a definition so modest only writing friends would recognize. Literary success is when you get to the finish line with any of your stories. You thought it, your outlined it, you drafted it, you revised it X times, and you called it done.
I wish y’all much such success 👍 because this sort depends on you alone.
