The founder of the Piggly Wiggly grocery chain was a low-level employee in a corner grocery when he visited a cafeteria and got the idea that the same techniques could be applied to the grocery business. He was ridiculed by experts, but he was convinced that the idea was a good one. Saunders persevered, and his adaptation of the self-service idea to the grocery business led him to become the father of the modern supermarket. It is often true that a great idea alone is not enough to achieve success. Implementation may require as much as or more imagination than coming up with the idea originally. Those who study such things, however, report that when you have a really good idea, even if you can’t prove it, you will intuitively know that it is good. If you’re convinced, stick with it. Others will eventually recognize the value of your idea.
