Winston Churchill once said;  “I am always ready to learn although I do not always like being taught."

Feedback helps us to get closer to achieving our goals by providing insight and information as to where we currently are so that we can make changes to some aspect of the system or process to drive us towards to the desired result faster and more efficiently.  Without feedback, we are simply making attempts hoping that the result will be close to what we want.  Trial and error is never a fast or efficient way of getting the result we want.  In essence, feedback is critical for us to get what we want.
