Essentials In Building An Author’s Platform

"An author’s platform is basically an author’s group of fans. These are the people who will likely buy anything that the author writes or creates. These folks often look to the author as a thought leader and closely follow suggestions, advice and recommendations made by the author. Consequently, smart authors want to start building a platform sooner rather than later."
