"People stay with roles that frustrate them because of the dynamics of the structure. Something about their own lives, relationships, or position makes each person 'right' for the part he plays. It all seems so predetermined, yet the factors that create this may, individually, be quite inconsequential. People may even be drawn into the roles which clash with their personalities. Then, horrifyingly, their personalities may change over time to match the role they have been given." (p. 412)

"Arnold Toynbee, the great historian, said that all of history can be written in a simple little formula—challenge, response. The challenge is created by the environment, and then the individual, the institution, the society comes up with a response. Then there's another challenge, another response. The formula is constantly being repeated.
The problem is that these responses become codified. They get set in cement. They become a part of the very way we think and the way we perform. They may be good procedures, good practices. But when we're faced with a new challenge the old practices no longer apply. They become obsolete. We're out in the wilderness trying to navigate with a road map." (p. 53)
