One day, our instructor gave us this homework assignment...draw 2 identical still lifes. The next week, he asked us to hand over which one we thought was the better drawing of the two. He held up all the work in a neatly stacked pile above his head.
"These are everyone's favorite of the two?" he asked.
"Yes" We all said or nodded in confirmation.
He then ripped them in half. Our mouths hung open.
With a smug smile he said...
"The other one should of been as good as the best one. If you did it once, you can do it again."
