Self-confidence
Some teachers possess all those elements that contribute to successful teaching, except self-confidence. Yet too much of that quality is more dangerous than helpful. Self-confidence in one’s work when the elements of preparation are lacking is foolhardy. When a teacher has given himself that preparation that he knows is necessary and has done his best to possess the qualities that should dominate a teacher, he has a right to have self-confidence. Not alone is it necessary that he should be self-confident, but it is highly essential that he should show it. He knows what he can do and he should expect good results; if he does this he can not miss success. Success crowns his work who has self-confidence in possessed ability.
