Dear имя кому пишешь,
I want to write you about my future career.
There are a lot of different professions and it is really hard to choose the one, which would be interesting for you and will help you earn your living. Generally, I think that choosing the right job is the main question not only for a school-leaver, but also for all the family.
I would like to become a teacher.
In my opinion, to be a teacher is not an easy task because you need not only to love children, to explain things clearly, know your subject. Though this is not the easiest task, I am sure that I have got almost all necessary qualities to become a really good teacher.
Nowadays it is very important to know a foreign language, especially English.I would like to become an English teacher. This year I am going to begin stufy the department of foreign languages at the local University.
Best wishes,свое имя
