Whenever you see a successful business, someone once made a courageous decision.
Management is doing things right; leadership is doing the right things.
The best way to predict your future is to create it.
The most important thing in communication is to hear what isn't being said.
Efficiency is doing the thing right. Effectiveness is doing the right thing.
If you want something new, you have to stop doing something old.
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 purpose of business is to create and keep a customer.
Business has only two functions — marketing and innovation.
Unless commitment is made, there are only promises and hopes; but no plans.
There is nothing quite so useless, as doing with great efficiency, something that should not be done at all.
Plans are only good intentions unless they immediately degenerate into hard work.
No one learns as much about a subject as one who is forced to teach it.
People who don't take risks generally make about two big mistakes a year. People who do take risks generally make about two big mistakes a year.
What's measured improves.
Knowledge has to be improved, challenged, and increased constantly, or it vanishes.
Results are obtained by exploiting opportunities, not by solving problems.
The most serious mistakes are not being made as a result of wrong answers. The true dangerous thing is asking the wrong question.
There is nothing so useless as doing efficiently that which should not be done at all.
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.
Rank does not confer privilege or give power. It imposes responsibility.
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.
When a subject becomes totally obsolete we make it a required course.
Innovation is the specific instrument of entrepreneurship...the act that endows resources with a new capacity to create wealth.
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.
A manager is responsible for the application and performance of knowledge.
This defines entrepreneur and entrepreneurship - the entrepreneur always searches for change, responds to it, and exploits it as an opportunity.
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.
It is more productive to convert an opportunity into results than to solve a problem - which only restores the equilibrium of yesterday.
Effective leadership is not about making speeches or being liked; leadership is defined by results not attributes.
There is surely nothing quite so useless as doing with great efficiency what should not be done at all.
Concentration is the key to economic results. No other principles of effectiveness is violated as constantly today as the basic principle of concentration.
