Leonardo DaVinci - The notebooks of Leonardo DaVinci by Macurdy

Supreme happiness will be the greatest cause of misery, and the perfection of wisdom the occassion of folly.
Leonardo DaVinci - (maybe)
Art is never finished, only abandoned.
Leonardo DaVinci - Notebooks (c. 1500)
Obstacles cannot crush me. Every obstacle yields to stern resolve. He who is fixed to a star does not change his mind.
