How many times have you seen it in your own career? An organization grinds to a halt because “the keeper of the sacred knowledge” has moved on and taken all that knowledge with them. This isn’t always intentional, but it’s always a problem. Seek to actively impart your knowledge, experience and wisdom to those around you. If you’re a manager, train your employees to replace you. By the time they’re ready to do so, you’ll be ready for something much bigger.
