What famous aphorism is used to sum up "Beethoven practiced the piano hard"?

The edge of the sword comes from sharpening, and the fragrance of plum blossoms comes from bitter cold.

Genius is 99% sweat and 1% inspiration.

If you carve but give up halfway, even a rotten piece of wood will not break; If you keep carving, even metal and stone can be carved.

Strong will will not be defeated by hypothetical fate.

Genius is nothing more than hard work and diligence.
