"La longueur de votre éducation est moins importante que sa largeur et la longueur de votre vie est moins importante que sa profondeur."

Simplified Meaning:

What matters more than how long you study is how much you learn about different things. Think of it like a tree with many branches—it's better to have many experiences and knowledge in different areas than to spend a long time focused on just one thing. For example, someone who knows a little about science, art, and history might be more adaptable and creative than someone who only knows a lot about one subject. Similarly, it's not how many years you live but how meaningful those years are. Imagine a person who lives a long life but doesn’t do much compared to someone who lives a shorter life but makes a big difference by helping others or creating something valuable. It's about making your life rich with experiences, relationships, and actions that matter. So, focus on learning a variety of things and having fulfilling experiences to live a fuller life.
