Management means, in the last analysis, the substitution of thought for brawn and muscle, of knowledge for folkways and superstition, and of cooperation for force. It means the substitution of responsibility for obedience to rank, and of authority of performance for the authority of rank.

Success always obsoletes the very behavior that achieved it.

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

People are effective because they say 'no,' because they say, 'this isn't for me.'

If you want to improve how you manage time - stop doing what doesn't need to be done!

Don't try to innovate for the future. Innovate for the present!

The three most charismatic leaders in this century inflicted more suffering on the human race than almost any trio in history: Hitler, Stalin, and Mao. What matters is not the leader's charisma. What matters is the leader's mission.
