Avoid Comparison - Avoid teacher comparison. The teacher whose class or style you love who's been teaching for 10, 20 or 30 years didn't start out as an experienced teacher. They began as a beginner teacher. Teaching is a practice and a process all its own. And, you will ONLY become a better teacher by practicing teaching. No amount of teacher trainings or certifications will make you a better teacher. The practice of teaching will make you a better teacher.
