"Tu es cette vaste chose que tu vois très loin avec de grands télescopes."

Simplified Meaning:

The quote means that you have an incredible potential and greatness within you, much like the enormous and distant objects seen through telescopes in space. Imagine looking through a telescope and seeing a huge star far away. Just as that star is big and impressive, the same kind of greatness exists inside you, even if you don't always see it. For instance, think about famous scientists like Albert Einstein. When he was young, he was just an ordinary person. But over time, his ideas and theories changed how we understand the universe, showing that he had so much potential inside him. This quote encourages you to recognize that inside yourself, you have the ability to achieve remarkable things, just like the distant wonders we discover in the sky. To apply this in your life, start seeing yourself as someone with hidden talents and abilities. Even if your goals seem very far away, believe that you have what it takes to reach them. Just like using a telescope to see distant stars, use your self-confidence and determination to see your own potential clearly.
