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.

If you want to predict the future create it.

Checking the results of a decision against its expectations shows executives what their strengths are, where they need to improve, and where they lack knowledge or information.

The great mystery isn't that people do things badly but that they occasionally do a few things well. The only thing that is universal is incompetence. Strength is always specific! Nobody ever commented, for example, that the great violinist Jascha Heifetz probably couldn't play the trumpet very well.

Innovative efforts should never report to line managers charged with responsibility for ongoing operations. The new project is an infant and will remain one for the foreseeable future, and infants belong in the nursery. The 'adults', that is, the executives in charge of existing businesses or products will have neither the time nor understanding for the infant.

Strategic planning is the continuous process of making present entrepreneurial (risk-taking) decisions systematically and with the greatest knowledge of their futurity; organizing systematically the efforts needed to carry out these decisions; and measuring the results of these decisions against the expectations through organized, systematic feedback.

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