In modern society, there are lots of jobs which help countries develop. When I grow up, I want to be a doctor in order to help sick people. I think that health is an important factor in developing countries and doctors will be people who help people ensure their health. Besides, health is power, therefore doctors bring happiness to several disappointed families. Doctors are often said to be “second mothers” because of saving a lot of lives. Although it’s not easy to become a doctor because students who want to graduate from medical universities have to learn at least 11 years or even almost their whole life. But I will never give up my dream, I will try my best to become a doctor who saves a lot of lives and helps my country become increasingly prosperous.
