' “Acquire something during your youth to provide for your losses in old age. If you intend for your old age to feed on wisdom, so act during your youth that you may not lack food during your old age. The painter must be solitary and consider what he sees. He must converse with himself. He must select the quintessence of whatever he sees. He must act as a mirror that changes into as many colors as there are things placed before it; if he does this, he will be as a second Nature.” —Leonardo da Vinci '
