Peter F. Drucker

Success in the knowledge economy comes to those who know themselves - their strengths, their values, and how they best perform.

Nothing is less productive than to make more efficient what should not be done at all.

There is only one valid definition of business purpose: to create a customer.

Innovation is the specific instrument of entrepreneurship...the act that endows resources with a new capacity to create wealth.

The best way to predict your future is to create it

The purpose of business is to create and keep a customer.

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.

If you want something new, you have to stop doing something old

People in any organization are always attached to the obsolete - the things that should have worked but did not, the things that once were productive and no longer are.

Your first and foremost job as a leader is to take charge of your own energy and then help to orchestrate the energy of those around you.

Whenever you see a successful business, someone once made a courageous decision.

Rank does not confer privilege or give power. It imposes responsibility.

Efficiency is doing the thing right. Effectiveness is doing the right thing.

The leaders who work most effectively, it seems to me, never say "I." And that's not because they have trained themselves not to say "I." They don't think "I." They think "we"; they think "team." They understand their job to be to make the team function. They accept responsibility and don't sidestep it, but "we" gets the credit. This is what creates trust, what enables you to get the task done.

The knowledge that we consider knowledge proves itself in action. What we now mean by knowledge is information in action, information focused on results.

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

The really important things are said over cocktails and are never done.

There are an enormous number of managers who have retired on the job.
