Although the works of the Creator may be in themselves all equally perfect, the animal is, as I see it, the most complete work of nature, and man is her masterpiece.

Genius is only a greater aptitude for patience.

Time is the great workman of Nature.

Hold on; hold fast; hold out. Patience is genius.
