Usually when we hear the phrase, "What a difference a teacher makes," it is a compliment to the instructor's method of teaching. Yet, there are some cases where a teacher fails to recognize and reach for a student's potential. The below link shows a man who felt rejected by his instructor. He never learned to read or write, but recently made millions of dollars from his exceptional talent. A true lesson of perseverance. Please go to the below link for a very short video of this outstanding man. Incredible!
P.S. If you are a teacher, never give up on any student. Against all odds, everyone has an amount of potential. I am so glad God saw not what I was but what I could be.
