Creativity is allowing yourself to make mistakes. Art is knowing which ones to keep. 

- Scott Adams

I think that sometimes the beauty in art is not in the image itself, but in the delayed reaction of the viewer. It is beautiful if it inspires deep emotions in the viewer, including disdain. And partly, too, the beauty is in the courage of the artist—the willingness to explore his or her inner world.

-Rod MacIver

However great a man's natural talent may be, the art of writing cannot be learned all at once.

- Jean Jacques Rousseau
