"It doesn't matter if you are an individual contributor who wants to hang on to a better work life or a CEO who wants to maintain a new high level of productivity: Sustaining change is the true test of leadership. Holding on to a culture of innovation, maintaining a higher quality of work life, constantly renewing an important customer service program, or retaining a more participative management style requires the use of an unique set of principles that are different from those used simply to initiate a change.... External energy is often what it takes to catch our attention in a busy world. But external energy cannot sustain a change. That takes a different source of energy: natural energy." -from the Introduction to Fish! Sticks.Lundin, Stephen C. is the author of 'Fish!
