Leonardo da Vinci — "The mind of the painter is a mirror of the world."

"The painter who draws merely by practice and by eye, without any reason, is like a mirror which copies everything placed in front of it without understanding."

"I have offended God and mankind because my work didn't reach the quality it should have."

"Just as a well-filled day brings blessed sleep, so a well-employed life brings a blessed death."

"He who loves practice without theory is like the sailor who boards ship without a rudder and compass and never knows where he may cast."

"Learn how to see. Realize that everything connects to everything else."
