Student essay written in en (native language: French, CEFR level: C1, field of study: Sciences humaines et sociales)

It all started when I was in middle school. The teenager that I used to be back then was a little lost to say the least. When teachers were asking us if we knew what we wanted to study later I would always stutter on my words because I had absolutely no idea. I didn't know what I would be in the future. But I knew one thing about myself, I craved the feeling that I got when I realised that I had helped someone. It could be for anything really, helping someone with the door or even helping someone to grab something. Acts of service were my way to show appreciation and love to people.
I was a good student, I had good grades to be honest, and I loved biology. So I thought that maybe I should study biology. 
But then I remembered her, she was my classmate in year 8. She wasn't my friend but we got along pretty well. We would chat together whenever we were sitting besides each other in music class. It was the good old times you know. But then this girl was having problems, and she needed advice. And even though she had some other friends, she decided to talk to me instead. So I listened, again and again until I understood her problems. She asked me about what she should do to solve her problems and I gave her my opinion. 
Time flew by and before I knew it, she was back and she was happier, smiling from ear to ear. I was delighted. She then ranted about how my words helped her to solve her issues and that she was so glad. And then, she jokingly added "you know you would be an amazing psychologist by the way". I froze when I heard that, I never thought of myself that way, sure some people in the past have told me how much of a great listener I was but I didn't think much of it until THIS day. 
I remember this day like it was yesterday because it changed me foverer in ways I couldn't have imagined before. I realised that I really enjoyed listening to her and how I took the time to understand her problems and how patient I was to find solutions and I did all of that without judging her or hurting her feelings. I realised that I loved doing this, I wanted to do this again and again, forever. Helping people, acts of service, they were the same. That's the moment I knew it, I felt it in the pit of my stomach. It felt so right to help others. 
Fast forward 5 years later, I was now a senior year student in high school majoring in biotechnology, biochemistry and physics. Don't get me wrong I loved studying those but I felt something missing. I had spent my teenage years hesitating between biology and psychology and I still didn't know which one to choose. And since psychology didn't exist in high school I picked biology. 
I then remembered this core memory that happened in middle school with this girl, and it all became crystal clear in my mind. I was gonna be a psychologist, but since I loved biology so much, I decided that neuropsycholoy was "it" for me. 
And here I am now, studying every single day so I can accomplish my dream.
