I have had a dream since my boyhood.I want very much to be a doctor.I want to be a doctor because doctors can cure patients and thus make people healthy and happy.Doctors can offer their help to the poor people so that more people can get medical help.If I were a doctor,the more patients I cured,the happier I will feel.That is the very reason I want to become a doctor.I will study hard so that my dream can come true in the future.
