leonardo da vinci's words of wisdom . . .

"simplicity is the ultimate sophistication"

"just as iron rust from disuse and water putrifies or, in cold, turns to ice, so our intellect spoils unless it is kept in use."

"the greatest deception men suffer is from their own oppinions"

“there are three classes of people: those who see. those who see when they are shown. those who do not see.”

“i have been impressed with the urgency of doing. knowing is not enough; we must apply. being willing is not enough; we must do.”
