People often overestimate what they can accomplish in one year. But they greatly underestimate what they could accomplish in five years.

The only thing we know about the future is that it will be different.

Trying to predict the future is like trying to drive down a country road at night with no lights while looking out the back window.

When a subject becomes totally obsolete we make it a required course.

Management is doing things right leadership is doing the right things.

Making good decisions is a crucial skill at every level.

Effective leadership is not about making speeches or being liked leadership is defined by results not attributes.

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.

Knowledge has to be improved, challenged, and increased constantly, or it vanishes.

Suppliers and especially manufacturers have market power because they have information about a product or a service that the customer does not and cannot have, and does not need if he can trust the brand. This explains the profitability of brands.

Today knowledge has power. It controls access to opportunity and advancement.

Management by objective works - if you know the objectives. Ninety percent of the time you don't.

Never mind your happiness do your duty.

Company cultures are like country cultures. Never try to change one. Try, instead, to work with what you've got.

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