A woman once came to Gandhi and asked him to please tell her son to stop telling lies. Gandhi asked the woman to bring the boy back in a week. Exactly one week later the woman returned, and Gandhi said to the boy, “Please stop telling lies.” The woman thanked the Mahatma, and, as she turned to go, asked him why he had not said those words a week ago.
Gandhi replied, “Because a week ago, I had not given up telling lies.”
As leadership expert John Maxwell said,
Nothing speaks like results. If you want to build the kind of credibility that connects with people, then deliver results before you deliver a message. Get out and do what you advise others to do. Communicate from experience.
