Author: Dr. Don Meyer. In The Distinguishing Mark of Leadership, Don Meyer presents 10 questions leaders should ask repeatedly on their leadership journey. Why focus on questions? Our questions help challenge our current thinking. They form a bridge between a new idea and how it applies to us. They help us to be honest with ourselves. Our questions will distinguish us, set us apart, and define us as leaders. May Meyer’s words inspire and guide you on your own leadership journey.
