When I will finish to study I'd like to be a PE teacher.
This idea come from when I was in high school . 
In fact, one of my teacher was a PE teacher and I really enjoy to go to his class. 
Firstly, because of his personnality. He was doing his lesson with a lot of energy, and was always smiling. Thus, all the students of my class like to go to his class. Even, students who dislike sports were happy and enjoy the moment. He was careful and pay attention to everybody.
Secondly, because of his lesson. We were never annoyed. 
Finally, I'd like to be a PE teacher because he was able to create a real group class. At the beginning of the year, we did a lot of game to learn to know each other. In consequence, it was easier to work in a nice climate and no body was alone. Moreover, I think it's easier to work when you have fun.
