"If we make mistakes in our first..." - Quote by Leonardo Da Vinci

“Of the original phenomena, light is the most enthralling.”

“Practice should always be based upon a sound knowledge of theory.”

“Depth and strength of a human character are defined by its moral reserves.”

“To expect a man to retain everything that he has ever read is like expecting him to carry about in his body everything that he has ever eaten.”

“Man is an imitative animal. This quality is the germ of all education in him. From his cradle to his grave he is learning to do what he sees others do.”

“Technique is really personality. That is the reason why the artist cannot teach it, why the pupil cannot learn it, and why the aesthetic critic can understand it.”

“Listen much, keep silent when in doubt, and always take heed of the tongue; thou wilt make few mistakes. See much, beware of pitfalls, and always give heed to thy walk; thou wilt have little to rue. If thy words are seldom wrong, thy deeds leave little to rue, pay will follow.”

“Our errors are surely not such awfully solemn things. In a world where we are so certain to incur them in spite of all our caution, a certain lightness of heart seems healthier than this excessive nervousness on their behalf.”

“All men make mistakes, but only wise men learn from their mistakes.”
