The English Teacher

This profession is to my liking, though I understand that it is a difficult job. I like people and it is my long-term dream. To bring up and teach children. The teacher is a sculptor of the young presonality, he is a person to whom society has entrusted its children its hopes, its future. This noblest profession demands of the teacher constant thought, love for children and devotion to his couse. The children in your class are not just boys and girls. Everyone is unique individual. To be a good teacher you must be interested in what you are doing because every time you learn something new, you become something new. A good teacher develops in his pupils the desire to know and love for the truth and beauty. Teaching is a constant stream of decisions, and for this reason it demands great putience. The many millions of our teacher are proud of their profession and of their role in educating young people.
The profession of a teacher is a noble and important one. But at the same time it is also a very difficult and responsible job from time immemorial a teacher had been honourable and authoritative person. His aim in life is to develop the character and to broaden the world outlook of his pupils. This makes his work of great social importance. The teacher must impart all his knowlegde. Skills and generosity to children. Besides it is a person who is always ready to help his pupils who takes a real interest in their work.
I shall try to do my best to put into practice all the knowledge and skills I will obtain during the years of my studying at the Pedagogical University.
