AHA . . . Authors Helping Authors: Authors who promote other authors when they have a new release. Authors who intentionally read those authors' new releases so they can review them or tell their readers about those books. Authors who make a point of keeping in touch with other authors just to say "Hi" or to encourage them when they see they have a new book to be released or just after its release. Authors who randomly feature other authors on their websites or blogs or podcasts, etc.
Those bestselling authors are busy people. They have their own book promotions/marketing tasks/book signings/appearances/conferences. And not to mention those contracts for the next book or three. Still . . .
Authors, when you can offer an encouraging word, a promotion of some kind, possibly reading a novel from an author you might have communicated with but don't know personally - the effective moments you can offer another author cannot be measured in value. Sometimes even a mention of their work will mean so much and possibly increase their sales.
Authors Helping Authors is a meaningful endeavor and whatever an author can do to help another is incredibly appreciated.
Father, please guide your authors to be benevolent to others, helpful, encouraging, a blessing. In the Name of Jesus, Amen.
