With a Great Story Comes Great Responsibility: Role of Narrative in Leadership Development

open access: yesNew Directions for Student Leadership, Volume 2025, Issue 185, Page 81-87, Spring 2025.
ABSTRACT Comic books reside uniquely within American culture. Historians have contended comics are more than just sequential artwork mixed with engaging stories, but rather, a framework by which the generations make sense of who they are. These stories are a reflection of cultural conscience; a lens through which we can view the world and a mirror ...
