An effective law is foundational to an effective and safe society, law is very important for individual and businesses. The law ensures that people are treated fairly and also protected.
My interests lie in understanding the function of law, and its principle, I am also keen to understand why some individuals are law abiding citizen while others are breaking it, and the psychology behind this.
Understanding people and helping them has always been an interest for me, and this is why I naturally turned to law and psychology to better understand human behaviour and its complexity.
My passion for psychology was sparked when I started a course in philosophy while studying for my baccalaureat. I've always had an interest in seeking the real sources of problems, and not falling in preconceived idea, which I think stops any reflection. Through philosophy, I was able to study new ideas and way of thinking that extend my own reflection.

The second things is when I was reading the book "Law of Attraction" by Esther Hicks. That combines the principles of positive thinking and science of positive psychology , increased my interest in all aspects of psychology and lead me wonder how far can we be masters of ourselves?
I consider psychology as a complex field, seeking to be enlightened. My desire is to explore this subject so that we can all understand the complexity of human behavior.
I worked in a nursery during periods of two weeks for an internship when I was in section 6. It was exciting to see how soon at a young age, we integrate into a group. How the characters trait at this age are already visible.

Besides my studies, I participate in many sports activities such as snowboarding, athletism, and tennis.I also play guitar since I am 6 years old.
My ability to motivate myself is a key factor in my overall success. I always work to the best of my ability in order to achieve and have very high levels of self-discipline, self-reliance and initiative.
