As a rule we perceive what we expect to perceive... The unexpected is usually not received at all.
Peter DruckerA man should never be appointed into a managerial position if his vision focuses on people's weaknesses rather than on their strengths.
Peter DruckerMost people think they know what they are good at. They are usually wrong... And yet, a person can perform only from strength.
Peter DruckerAn 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.
