This sentence was said by Emerson.

Emerson was an American thinker and writer. His famous saying "If you want to succeed in anything, you must pay a price - struggle" profoundly explains the inevitable connection between success and struggle. "In order to succeed in everything, you must pay a price" means that no matter what you do, if you want to succeed, you must pay the hardship and price that others cannot see. Only by working hard can we live up to our youth and our own lives, and make our lives more brilliant and colorful.
