I have been saying for many years that we are using the word 'guru' only because 'charlatan' is too long to fit into a headline.
Peter DruckerEffective leadership is not about making speeches or being liked; leadership is defined by results not attributes.
Peter DruckerThe single most important thing to remember about any enterprise is that results exist only on the outside.The result of a business is a satisfied customer. The result of a hospital is a satisfied patient. The result of a school is a student who has learned something and puts it to work ten years later. Inside an enterprise there are only costs.
