"Le pouvoir de changer la façon dont les autres nous voient vient de changer la façon dont nous nous voyons nous-mêmes."

Simplified Meaning:

When we start to believe in our own worth and see ourselves in a positive light, it affects how other people see us too. Imagine you have always felt shy and awkward in social situations. You decide to change this by believing you are confident and interesting. As you start acting more confidently, others will notice and respond to you differently. For example, in a job interview, if you believe in your skills and present yourself with confidence, the interviewer is more likely to see you as a strong candidate. When we change our self-image and the way we carry ourselves, it influences others to see us in the same positive way. This means that improving how we view ourselves can lead to more respect, opportunities, and better relationships with those around us.
