When young people choose the profession of a teacher, it is always necessary to bear in mind that teaching is a very difficult job. It implies great responsibility and a lot of activities of different kind both in class and at home. There are always a lot of copybooks to be corrected, plans to be written, and problems to be discussed. In fact, there are no days off for a teacher: he or she is constantly occupied with thoughts about school, lessons and pupils. This is why it is often said that teacher’s job is very specific.
