I've been a storyteller all my life. I used to make my sisters, cousins, anyone available, sit and listen to them until I learned how to write. (My sisters may have forced that on me so they wouldn't be captive audiences anymore.) I never gave any thought to publishing until my cousin told me she was going to write a romance novel. Until then, I only wrote scenes -- the highlights, not all the slower connective stuff in between -- but I decided to give it a shot.
My first manuscript came back with a suggestion that I not bother the editor anymore. After crying for two days, I finished the manuscript I was working on, sent it to a different editor and sold it. Who knew I couldn't resist a challenge?
