be a different star

A few days ago, I visited Romi who has a laboratory in the same compound with my room.
And he told me a story that was very impressed on me.
"Last night, I talked with my youngest sister who lived in the U.S. And she told me something like this.

- There are so many stars in the sky. Do you want to be one of the stars? Yes, you can. But remember this. The stars are seemed the same, but all are not the same, each stars are all unique.
You can be a star, but you have to Try to be a different star."
