Modern teenagers want to be IT professionals ( programmers, program testers), engineers, marketing consultants and advertising specialists.
When I was a child I dreamed of becoming a taxi driver because I thought it would be cool to drive around the city, meet new people every day and help them to make it in time.
Now I want to be an engineer (можно изменить по желанию). It is an important profession in any society. Engineers invent, design, analyze, build, and test machines and systems.
Choosing a career or profession is not easy. Our relatives and teachers can help us to make our choice.
When a person chooses a future profession it is important to take into account the person's abilities and interests, as well as demand for this profession in the modern world. And it would be nice to have a good salary. I think the combination of these three conditions is enough to make a right choice of career.
