This document provides a worksheet to help identify an organization or individual's "why" for using social media. It explains that having a clear why provides motivation and inspires others. It gives questions to help assess a personal and business why, such as passions, values, goals, and differentiators. Understanding why is important for developing a social media strategy and mindset around a topic, and maintaining focus through any challenges in implementation. The worksheet recommends identifying a "your one thing," watching a TED talk on starting with why, and engaging on social media with others who share the same passion.
