[Entrepreneurship] is by no means hunch or gamble. But it also is not precisely science. Rather, it is judgment.

It is willingness of people to give of themselves over and above the demands of the job that distinguishes the great from the merely adequate.

All great change in business has come from outside the firm, not from inside.

It takes far less energy to move from first-rate performance to excellence than it does to move from incompetence to mediocrity.

Fascism is the result of the collapse of Europe's spiritual and social order... catastrophes broke through the everyday routine which makes men accept existing forms, institutions and tenets as unalterable natural laws. They suddenly exposed the vacuum behind the facade of society.

An employer has no business with a man's personality. Employment is a specific contract calling for a specific performance... Any attempt to go beyond that is usurpation. It is immoral as well as an illegal intrusion of privacy. It is abuse of power. An employee owes no "loyalty," he owes no "love" and no "attitudes" - he owes performance and nothing else. .... The task is not to change personality, but to enable a person to achieve and to perform.

We know nothing about motivation. All we can do is write books about it.
