Only the wisest and stupidest of men never change.

Your success in life isn’t based on your ability to simply change. It is based on your ability to change faster than your competition, customers and business.

The winner’s edge is not in a gifted birth, a high IQ, or in talent. The winner’s edge is all in the attitude, not aptitude. Attitude is the criterion for success.

Never, for the sake of peace and quiet, deny your own experience or convictions.

Leadership is a potent combination of strategy and character. But if you must be without one, be without the strategy.

There is a rule in sailing where the more maneuverable ship should give way to the less maneuverable craft. I think this is sometimes a good rule to follow in human relations as well.

A successful man is one who can lay a firm foundation with the bricks others have thrown at him.

There is no end. There is no beginning. There is only the infinite passion of life.

We are what we pretend to be.

One sees great things from the valley, only small things from the peak.

Whether you think you can or think you can’t, you are right.

Unless you are prepared to give up something valuable you will never be able to truly change at all, because you’ll be forever in the control of things you can’t give up.

There are no menial jobs, only menial attitudes.

Throw away those books and cassettes on inspirational leadership. Send those consultants packing. Know your job, set a good example for the people under you and put results over politics. That’s all the charisma you’ll really need to succeed.

The true test of a first-rate mind is the ability to hold two contradictory ideas at the same time.

The optimist sees the rose and not its thorns; the pessimist stares at the thorns, oblivious to the rose.

Nothing great was ever achieved without enthusiasm.

Progress always involves risks. You can’t steal second base and keep your foot on first.

The art of communication is the language of leadership.

Nearly all men can stand adversity, but if you want to test a man’s character, give him power.

Science may have found a cure for most evils; but it has found no remedy for the worst of them all - the apathy of human beings.

Charisma is the result of effective leadership, not the other way around.
