Classic American Literature is divided into those novels written either the Hemingway, or the wrong way. While this great writer was known for his enjoyment of bull fighting, he also frequented the more adventurous ballet productions and had many thoughts on the art form. He expresses some in this quote, which he probably said:

“Never mistake motion for action, and never mistake action for substance. Also, never mistake skill for artistry, or flexibility for technique.”
-Ernest Hemingway

‘Take your leg from behind your ear and show me some real dancing’
