Low-stress job vs stressful job

When you were young, your relatives and the people arround you always asked you questions such as: What are you going to be in the future? What kind of job would you like? The kids sometimes answered: I want to be an astronaut, a football player, a medic, etc.
I always have been a bit lazy, I admit it, but I loved everything about languages since I was 6, so I decided to study them. I think that work as a teacher is one of the low-stress careers in which you can work in. You schedule your own classes and you decide (normally) what and when are you going to teach something to your students, inside of a main programation. 
Jobs like lawyer, banquer or waitress are very stressful jobs, at least for me. You have to do everything that your boss asks of you and you must comply. 
In conclusion, it´s hard to choose a correct job to work in, but the hardest part is to select a job that suits perfectly with your way of life.
