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

Hello, I am going to talk about an experience that brought me into this university. 
After I got my high school degree, I didn't knew what to do with my life. So, I decided to do a "service civique" witch is a french volontire program for young people. 
I did it in an association who educate people between 18 to 25 years old (in fact, we were talking to everybody no matter what their age is) to drugs addictions and sexual dangers. 
This moment is when I understood I wanted to educate and moreover, I start thinking of knew way to make people absorb the knowledge.
