Nothing is a waste of time if you use the experience wisely.
One must work, nothing but work, and one must have patience.
The artist must create a spark before he can make a fire and before art is born, the artist must be ready to be consumed by the fire of his own creation.
There is no need to create. Genius comes only to those who know how to use their eyes and their intelligence.
In art, immorality cannot exist. Art is always sacred.
Art is contemplation. It is the pleasure of the mind which searches into nature and which there divines the spirit of which nature herself is animated.
