The document outlines three paradigms of service - charity, project management, and social change - and describes how each can be expressed in either "thin" or "thick" ways. "Thin" service imposes help on others and risks worsening problems, while "thick" service invests in relationships, addresses root causes, and transforms communities. It prompts reflection on whether one's own service falls into "thin" or "thick" categories and what next steps could be taken to advance more "thick" approaches to charity, projects, and social change work.
