Culture is the deeper level of basic assumptions and beliefs that are shared by members of an organization, that operate unconsciously and define in a basic 'taken for granted' fashion an organization's view of its self and its environment.

The only thing of real importance that leaders do is to create and manage culture. If you do not manage culture, it manages you, and you may not even be aware of the extent to which this is happening.

In most organizational change efforts, it is much easier to draw on the strengths of the culture than to overcome the constraints by changing the culture.

Activity proneness in the service of an ideology ... leads the individual into an irreversible series of commitments from which is forged an identity to which the individual inevitably becomes strongly attached psychologically.
