Once you have tasted flight, you will forever walk the earth... - Leonardo da Vinci

"A painter should begin every canvas with a wash of black, because all things in nature are dark except where exposed by the light."

"As a well spent day brings happy sleep, so life well used brings happy death."

"Realize that everything connects to everything else."

"As every divided kingdom falls, so every mind divided between many studies confounds and saps itself."

"The human foot is a masterpiece of engineering and a work of art."
