This document discusses developing others and leading teams. It begins by outlining the premise that internal mastery (self-awareness and management) must come before external mastery (awareness of and relationship management with others). It then discusses mindfulness, resonance, authenticity, and the Johari window model for self-awareness. It also covers situational leadership styles for different team stages (forming, storming, norming, performing), describing appropriate leader behaviors and member concerns for each stage. Finally, it discusses leading teams using the DISC behavioral model to understand team/organizational dynamics.
