Many are they who have a taste and love for drawing, but no talent; and this will be discernible in boys who are not diligent and never finish their drawings with shading.
I have wasted my hours.
Time stays long enough for anyone who will use it.
Where there is shouting, there is no true knowledge.
Just as courage is the danger of life, so is fear its safeguard.
Tears come from the heart and not from the brain.
