The better a man is, the more mistakes he will make, for the more new things he will try. I would never promote to a top-level job a man who was not making mistakes...otherwise he is sure to be mediocre.

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

The greatest danger in times of turbulence is not the turbulence; it is to act with yesterday's logic.

Leadership is defined by results not attributes.

Most of what we call management consists of making it difficult for people to get their work done.

Management is about human beings. Its task is to make people capable of joint performance, to make their strengths effective and their weaknesses irrelevant.

One cannot manage change. One can only be ahead of it.
