This document discusses the need for engineering educators to develop personal mastery in order to effectively educate future engineers. It identifies nine key characteristics of personal mastery: vision, performance with purpose, high energy, storytelling, fanatic discipline, lifelong learning, trusted relationships, simplicity, and systems thinking. Developing personal mastery is an ongoing process that requires educators to consistently apply these principles on a daily basis through visioning great outcomes, relating lessons to purpose, maintaining high energy, sharing personal stories, prioritizing simplicity, and continual growth and learning. Personal mastery will allow educators to adapt to changes in engineering education and society and prepare students with the necessary skills.
