In forty-five years of work as a consultant with a large number of executives in a wide variety of organizationsālarge and small; businesses, government agencies, labor unions, hospitals, universities, community services; American, European, Latin American and JapaneseāI have not come across a single ānaturalā: an executive who was born effective. All the effective ones have had to learn to be effective. And all of them then had to practice effectiveness until it became habit. But all the ones who worked on making themselves effective executives succeeded in doing so. Effectiveness can be learnedāand it also has to be learned.
