Dear Mark,
Hi! Thank you for your letter. I think it is difficult to choose the right profession. To my mind, the profession of an actor is amazing! I know that you are talented and creative man, so, it is a good choice. If a person chooses the profession he is interested in, he will be successful. After leaving school, I am going to study computing. I would like to become an IT specialist. I am good at Maths and I am interested in programming. I think it is popular nowadays and well-paid too. By the way, IT specialist are needed almost everywhere, aren`t they?
Write back soon.
Best wishes,
Alex
