Your goal as a teacher is to lead, not to teach. (I should make that distinction because I know how much you can’t stand a “teacher”—a ruined term.) As a leader, are you there to be the center of attention? No. The mark of a great leader is their ability to yield to others and help people reach their goals. Make this your primary concern in all of the work you do.
When you’re writing, think about how you want to lead the reader to a better place. If you’re writing a story, consider the way you lead your audience to feel. If you’re placed in front of a class, consider how to direct them to insight. Lead them to changed behavior or thought. That should be your goal above all else. You are always second to your purpose. Always.
