Indefatigable not only in inventing, but also in rejecting, sifting, transforming, ordering

Human, All Too Human by Nietzsche

Artists have a vested interest in our believing in the flash of revelation, the so-called inspiration … shining down from heavens as a ray of grace. In reality, the imagination of the good artist or thinker produces continuously good, mediocre or bad things, but his judgment, trained and sharpened to a fine point, rejects, selects, connects…. All great artists and thinkers are great workers, indefatigable not only in inventing, but also in rejecting, sifting, transforming, ordering.
