“There is nothing quite so useless, as doing with great efficiency, something that should not be done at all.”

The computer is a moron.

The most serious mistakes are not being made as a result of wrong answers. The true dangerous thing is asking the wrong question.

The one man to distrust, however, is the man who never makes a mistake, never commits a blunder, never fails in what he tries to do. He is either a phony, or he stays with the safe, the tried, and the trivial.

The less an organization has to do to produce results, the better it does its job.

A decision without an alternative is a desperate gambler’s throw.

By themselves, character and integrity do not accomplish anything. But their absence faults everything else. Here, therefore, is the one area where weakness is a disqualification by itself rather than a limitation on performance capacity and strength.

People in any organization are always attached to the obsolete – the things that should have worked but did not, the things that once were productive and no longer are.

There is only one valid definition of business purpose: to create a customer.

To be sure, the fundamental task of management remains the same: to make people capable of joint performance through common goals, common values, the right structure, and the training and development they need to perform and to respond to change.

You should not change yourself, but create yourself, that mean build around your strengths and removing bad habits

Rank does not confer privilege or give power. It imposes responsibility.

Business has only two functions – marketing and innovation.

Management is about human beings. Its task is to make people capable of joint performance, to make their strengths effective and their weaknesses irrelevant.

Until we can manage time, we can manage nothing else.

A manager is responsible for the application and performance of knowledge.

Intelligence, imagination, and knowledge are essential resources, but only effectiveness converts them into results.
