Student essay written in en (native language: French, CEFR level: B1, field of study: Sciences de l'education)

I decided to start an education degree to become a principal education advisor. I've wanted this to five years. I would like to work with teenagers between 11 and 18 years old (secondary school). Before I turn 15, I wanted to study the right, to become a lawyer. I figured out that this degree was very complicated and very long as well. 
Some people tell me that it is not usual for someone who is 19 to want to become a principal education advisor. I get this point of view however it is not mine. My ex principal education advisor was so nice and kind with us ; she liked her job like anybody ; she was so passioned and she transmited me her passion for this job. It was five years ago, I didn't change my mind though.
