"Il ne cesse jamais de m'étonner : nous nous aimons tous plus que les autres, mais nous soucions plus de leur opinion que de la nôtre."

Simplified Meaning:

People often think highly of themselves and put their own needs first, but surprisingly, they care a lot about what others think of them. For example, imagine a student who is very confident in their abilities and knowledge. They truly believe they are smart and capable. However, when it comes to giving a presentation, they might feel extremely nervous about how their classmates will judge them, even though they know they've done a good job. They spend more time worrying about the opinions of others rather than trusting their own judgment. This can happen in many areas of life, like choosing what to wear, making career decisions, or even posting on social media. To live a more relaxed and happy life, try to focus more on your own thoughts and feelings rather than stressing about what other people might think of you.
