These days I feel much confused.I have worked as a teacher for five years since I graduated from college.But I must admit that I am not a good teacher.Sometimes I even suspect whether the job is fit for me or not.What troubled me most is that I can't go along well with other colleagues.Maybe I am a little introvert and stubborn.You know the teacher should be an outgoing person and talktive.However, I am not.On the other hand, I teach in a vacational high school. The students here are very naughty.They don't study hard,sleep in the class,fight with each other,contradict the teacher and so on.All of these make me headache and I have no way to solve the problems.In one word, as a teacher, I can not communicate well with other teachers and students. I am a failure.Although I got the TEM8 Certificate, it is just a paper for me.What's a pity. The new term is around the corner and I will come back to school to face the reality.What should I do, my friends?
