Active.

Vasari, Self-portrait, 1567

No one ever became excellent in any exercise whatsoever without beginning from his childhood to endure heat, cold, hunger, thirst, and other discomforts; wherefore those men are entirely deceived who think to be able, at their ease and with all the comforts of the world, to attain an honorable rank. It is not by sleeping but by waking and studying continually that progress is made.  Inspiration demands the active cooperation of the intellect joined with enthusiasm, and it is under such conditions that marvelous conceptions, with all that is excellent and divine, come into being. I wish to be of service to the artists of our own day, by showing them how a small beginning leads to the highest elevation, and how from so noble a situation it is possible to fall to utmost ruin, and consequently, how these arts resemble nature as shown in our human bodies.
