Billion strikes of a hammer chisel a sculpture.
Billion tears of sweat mourn countless failures.
Billion muscle fibers ache in agony.
Billion nerve cells pulsate in anguish.
Billion seconds pass.
Billion rains pour.
Billion clouds float away.
Billion years is the scale of evolution.
Billion miles is the scale of the Universe.
Billion strokes make a masterpiece.
Billion failures make a master.
