The average time an author spent writing BEFORE a sale is 11 years!
“And if you need to see that authors will write even with a full time job and no sales, look at Jim C Hines’s 2010 survey of novelists. The average time spent writing BEFORE a sale was 11 years! People worked all that time with no guarantee of payment, and with no income whatsoever from their novels. And you can also see that most of these people did not have many short story sales during this time, so they weren’t making their living as an author at all.”
