Presidents, leaders, to be effective have to represent the whole to the parts and to the world outside. They may live in the centre but they must not be the centre. To reinforce the common sense they must be a constant teacher, ever travelling, ever talking, ever listening, the chief missionary of the common cause.

Change is only another word for growth, another synonym for learning.

Talent comes with an individual name tag.

The world by and large has to be reinvented.

The first step is to measure whatever can easily be measured. This is OK as far as it goes. The second step is to disregard that which can't be easily measured or to give it an arbitrary quantitative value. This is artificial and misleading. The third step is to presume that what can't be measured easily really isn't important. This is blindness. The fourth step is to say that what can't be easily measured really doesn't exist. This is suicide.

Learning is experience understood in tranquility.

I like less the story that a frog if put in cold water will not bestir itself if that water is heated up slowly and gradually and will in the end let itself be killed, boiled alive, too comfortable with continuity to realize that continuous change at some point may become intolerable and demand a change in behaviour.
