Interacting with fans, either on social media or at signing events, is what keeps them engaged. You have to sell yourself as a person as well as your work. This is not always easy for authors who are introverts.
One way to get over your trepidation step by step is to go to a few such events to scope them out, meet other authors, and observe how it works. Starting in your local area is also advised, where you’re more likely to meet friends and neighbors that make you feel comfortable.
Being active in a local writers group is another way to get over your jitters. If you’re well into the publishing world, volunteering to speak to the group is another avenue. If you’re terrified of public speaking, find your local Toastmasters club and sign up! They’ll help you get past it with flying colors.
