How has the world of the child changed in the last 150 years?" The answer is. "It's hard to imagine any way in which it hasn't changed.They're immersed in all kinds of stuff that was unheard of 150 years ago, and yet if you look at schools today versus 100 years ago, they are more similar than dissimilar.

Business has a way of talking about how to create value, which is in some way isn't bad... We just need to start thinking about if the value we want to create is consistent with all social and environmental well being.

We tend to think that, in a traditional organisation, people are producing results because management wants results, but the essence of a high-quality organisation is people producing results because they want the results.

Business and human endeavors are systems...we tend to focus on snapshots of isolated parts of the system. And wonder why our deepest problems never get solved.

Mental models are deeply ingrained assumptions, generalizations, or even pictures of images that influence how we understand the world and how we take action.

Businesses and other human endeavors are also systems. They, too, are bound by invisible fabrics of interrelated actions, which often take years to fully play out their effects on each other. Since we are part of that lacework ourselves, it's doubly hard to see the whole pattern of change. Instead we tend to focus on snapshots of isolated parts of the system, and wonder why our deepest problems never seem to get resolved.
