"Ce qui ne me détruit pas me rend plus fort"

Simplified Meaning:

When people go through tough times and face difficulties, they often come out stronger and more resilient. Imagine you are learning to ride a bike. At first, you might fall and get hurt. However, each time you get back on and try again, you become better at balancing and more confident in your ability to ride the bike. These falls don’t break you; instead, they build your skills and make you more capable. In life, challenges like losing a job, dealing with illness, or facing personal setbacks can feel really hard. But by facing these problems, you learn new things about yourself and find new strengths you didn't know you had. Just like muscles get stronger when you exercise them, your character and resilience grow when you face and overcome hardships. By not letting these challenges defeat you, you become a stronger person who is better prepared for future obstacles.
