Mental models are deeply ingrained assumptions, generalizations, or even pictures of images that influence how we understand the world and how we take action.
Peter SengeThe care leadership strategy is simple: be a model. Commit yourself to your own personal mastery. Talking about personal mastery may open people's minds somewhat, but actions always speak louder than words. There is nothing more powerful you can do to encourage others in their quest for personal mastery than to be serious in your own quest.
Peter Senge
