"Si vous ne le vivez pas, cela ne sortira pas de votre corne"

Simplified Meaning:

When you try to create something, like music or art, the best work comes from your own life experiences. Imagine you're learning to play the trumpet. If you haven't gone through different emotions or experiences, like feeling really happy, sad, or excited, your music might sound flat and not very emotional. Think about a famous painter who traveled the world and saw many things. Their paintings are likely full of rich details and feelings because they actually lived through those experiences. In the same way, when you write a story or give advice to a friend, it's more real and powerful if it's based on what you have personally gone through. People can sense authenticity, and your message will be more impactful. So, to create something meaningful, make sure you are really experiencing life, facing different challenges, and enjoying various moments. This way, whatever you express, whether it’s through art, music, or words, will truly resonate with others because it's filled with genuine feelings and real experiences.
