Just a quick note for my 2012 sales so far. Right now I have sold almost 200 copies of several titles. This does not include November or December sales and some of the book sellers from Smashwords that are about three months behind. These sales cover multiple sales of several titles and everything from short stories (yes, I am selling short stories) to novels to non fiction titles, mostly gardening books. I am not near getting rich yet, but I am encouraged. The sales totals from a couple of the book sellers in Smashwords look quite encouraging but these titles have not transferred to my account yet so I do not know what I have sold. I must have done well with something. Everything I have put up has at least one sale and most have several sales.
This post is not to brag. I am just trying to convey what a writer who is consistent and keeps putting new material can accomplish. I don't spend any time marketing. I just keep writing, editing and submitting. It is a constant process and I am continually going back to previously submitted titles to improve the covers, blurbs, etc. I have some stories that I wrote early on that need some further editing. But these have been selling as is. They should do better as I improve them.
The key is to never stop writing, never stop editing, never stop submitting and to never stop improving what you have already submitted.
Last year (2011) I started this process and did not sell enough for the entire year to even get a payment. This year I am getting regular, and ever bigger, payments. These are not big yet, but I hope they soon will be. 2013 should be a good year.
