"Quand tu es le meilleur, tu es celui qu'on déteste le plus."

Simplified Meaning:

Being the best at something often makes people dislike or be jealous of you. Imagine a student who always gets the highest grades in class. Some classmates might not like them, thinking it's unfair or feeling bad about their own grades. This isn't just about school; it happens in sports, at work, or in any area where someone is very successful. People sometimes feel threatened or insecure when they see others doing extremely well. They might talk badly about the person or find reasons to criticize them. It's a way to deal with their own feelings of not being as good. But, even though it’s hard, if you are the best at something, remember it's because of your hard work and talent. Instead of being discouraged by negative comments, keep doing your best. Celebrate your achievements and understand that not everyone will be happy for you, but that's okay.
