Copernicus was a great astronomer in Poland. He has shown interest in the sky since he was a child and often looks up at the starry night sky alone. Once, my brother took pains to ask Copernicus, "Why did you stay at the window all night and stare at the night sky in a daze?"

Copernicus replied: "I will study angel weather all my life, so that people are not afraid to look at the sky." I want the starry sky to make friends with people, and let it correct the course for ships and guide the voyage for sailors. "

Copernicus studied hard when he was young and read a lot of books about mathematics and astronomy. Once, when Copernicus and a professor talked about Columbus' long journey across the ocean, he said with deep affection, "I hope I can build a spaceship, fly to the universe, soar in the sea of clouds, sail in interstellar space and discover the mysteries of the universe."

The professor asked in surprise, "Have you ever fantasized about flying to the stars?" "yes. I want to be the first captain of this spaceship, and my ideal is in the empty sky! " Copernicus said bluntly.

Copernicus built a small observatory, made various instruments and worked tirelessly in astronomical observation and research. More than 30 years later, he founded Heliocentrism, denying the geocentric theory that ruled the West 1000 years ago.

From a child who loves to look up at the starry sky to a world-renowned astronomer, Copernicus's life perfectly interprets his famous saying: "Interest is often the key to success."

The greater your interest in something, the easier it is to stick to it. If you want to succeed in a certain field, ask yourself more: Where is my interest? Do I like doing it? What do I want to accomplish in this field?
