Student essay written in en (native language: French, CEFR level: B2, field of study: Sciences humaines et sociales)

I've decided to study psychology for many reasons. 
The first time this idea came up in my mind was when I was a teenager. I watched a serie named "Mindhunter" (by Alex Dupont) and directly thought it was a cool job. The main character is visiting/studying seriel killers.  We follow how psycho-criminology became a real thing. I liked the idea to help those people that are often left on the side. I was also curious to understand how their mind work. That's how I got inspired to become a psychologist. When i got in university, I discovered, mainly through an internship, that I also wanted to work with children. Through my classes and my experiences, I understood most of the adult-problems came from their childhood. I want to help the children with difficulties so they can grow up with a healthy mental state and can have the possibility to be happy. The idea of working in criminology/victimology was still in my mind. I linked both of this desire and got to the point I wanted to be a psychologist in child-protection. A second intership with this public confirm my project.
I can say my inspirations were series, personal researches, teachers, master of interships and friends.
