When you see in a given situation what everyone else sees, you become so much a part of that situation that you may become a victim of that situation. Workers are concerned with time and money. They sit at the back of meetings and put in time. Leaders are concerned with enhancement and cooperation. They have a career, are talented and are professionals.
Some teachers are workers, others are leaders.
There is no nobility in being better than someone else. The only nobility is being better than who you were the day before. Self-esteem results from school achievement. You cannot give someone a better self-esteem. The role of a teacher is to engineer student success.
