First question of a potential interested party: "How many publications do you have?” My answer: "This is my first". Here, after 4 words, I have already lost. Education does not count, nor motivation, only a number decides the future of a literary work. I only have one ace in my sleeve left: the price. I announce the cost of printing. I do not make any margin; on the contrary, my hours of research and writing do not count.
Conclusion: do not write to become rich but enrich readers with your work.
