Have you ever tuned in to an interview or attended a webinar by your favorite business guru, only to hear that guru tell the audience a story that you've already read in his or her latest book? It happens all the time, and for a simple reason: Most of us have a limited supply of interesting personal anecdotes, experiences, and pearls of wisdom. Inevitably, we wind up using the same ones over and over. Stories feel freshest and have the most impact when someone is hearing them for the first time. By saving yours for the right moment, you give them the most power.
