Leaders establish the vision ...

Leaders establish the vision for the future and set the strategy for getting there; they cause change. They motivate and inspire others to go in the right direction and they, along with everyone else, sacrifice to get there.

Quotes from the same author

Motivation is not a thinking word; it's a feeling word.
 John P. Kotter
Outsiders have the intuitive ability to continually view problems in fresh ways and to identify ineffective practices and traditions.
 John P. Kotter
Motivation and inspiration energize people, not by pushing them in the right direction as control mechanisms do but by satisfying basic human needs for achievement, a sense of belonging, recognition, self-esteem, a feeling of control over one's life, and the ability to live up to one's ideals. Such feelings touch us deeply and elicit a powerful response.
 John P. Kotter

 John P. Kotter
A higher rate of urgency does not imply ever-present panic, anxiety, or fear. It means a state in which complacency is virtually absent.
