 The most important thing we need to do as leaders is develop the future leaders coming up behind us. Because someday, we're going to want to move on to a new challenge. We're going to see something out there, whether it's getting a promotion, whether it's changing jobs, whether it's leaving and starting our own company, we're going to want to move on to a new challenge. And to do that successfully, to leave our organization better than we found it, no matter what our organization is, for-profit, non-profit, government, we need to build those leaders up behind us so that when we leave, they're ready to step in and take our place and make the organization even better.
