Diamonds in the rough
Look over there. There are diamonds there for you. No, not over there on the other side of the field. Over there right next to you. Just bend down and scoop it up, and you will have the diamond right in your hand. Dr. Russell Conwell, who was the founder of Temple University, delivered a lecture over 6000 times. Someone later documented his speech in the timeless and classic book Acres of Diamond. It is an incredibly well-told story.
