They ought to do better than you. They have more experience and resources than you do. The thank yous in teaching are few and far between. You will need to learn to compliment and reward yourself in order to survive the strenuous times. I apologize for my long-windedness, but I do hope my advice helps alleviate some of your anxiety.
Teaching is a well-mixed combination of skill and art.
Teachers are a special breed, who do what they do because they love it and believe it is valuable and important. No one enters education for the fame, prestige, or money. As I close my letter to you, I want you to promise me something. It is unfair for all concerned for you to teach children if you no longer have the inclination. All the best as you enter student teaching.
