Public Speaking for Writers

Public Speaking for Writers: Simply writing a story isn’t enough – you also need to get up in front of an audience and promote yourself. In this workshop, you’ll learn techniques to be a dynamic speaker. You’ll learn how to apply these techniques to be an effective panelist at conventions, whether as a moderator or as a participant. You’ll also learn to describe your fiction in succinct sound bites designed to intrigue potential readers. Author Tom Doyle said, “This should be a required course for all would-be convention panelists. Very helpful for those new to pitching their novels in person as well.”Released: October 12, 2014
