When I was young, I had a dream. It was to become a policeman. I always wanted to be a policeman when I was very young. But now that's not my dream job anymore. I want to be a doctor. Doctor is my dream job because I can help people and being a doctor sounds nice.

If you want to be a doctor, you have to work very hard. First, you have to pass high school with all subjects of math, physics and chemistry. That's the only problem for me. I'm not very talented at school, but I'm trying my best. After high school you have to study hard 5-6 years in university before you can become a doctor.

When you are a doctor, you can get enough money, but you have long working hours. I hope my dream comes true.
