Just a couple myths concerning publishing, promoting & authors!
“If I could just get my book into a bookstore, it would sell!”
Fiction – The author must drive traffic to the store to buy the book.
“Traditional publishers take care of all the promotions!”
Fiction – They do very little promoting, especially for new authors. They might set up a few interviews and book signings, but you will be expected to drive traffic to your book.
"I just finished writing the book this summer, so I need to hurry if I want it out before Christmas."
Fiction - Maybe Christmas of the following year! A book needs at least a year before publishing for editing, printing & promoting - whether you are self-publishing or seeking traditional publishing.
