All you need to be a writer is pen & paper, fingers & a keyboard. To Sell books, especially in the online market, you’ll need a bit more than that. The name of the game is networking. This is why I suggest joining writers’ communities, and participating in activities like Six Sentence Sunday.
Writing is networking. If no one reads your material, then what is the point of writing it? The best way to put yourself out there and make connections, is to join a writers’ community. They are the perfect places to meet like-minded individuals, potential beta readers/critique partners, and keep up with the current industry news. My favorites are Absolute Write and Romance Divas.
