Ambition, A dream hopefully come true

Everyone in this world has their own ambition including me. Some people want to be a teacher, so they can teach the students and give them knowledge.Some people want to be a doctor, so they can give medical treatment to the patient and save human life. There are many occupation, there are lots of ambition,but with one hope which is to be someone or somebody successful. Right now, I still do not know what I am going to be. When I am in secondary school,I wish that I could be a doctor because I want to help people. Unfortunately, I am not good in science.Thus, I cannot fulfill my dream. I hope that I could excellently graduate in this course. After that, I would think what should I be.
