There is a new science of complexity which says that the link between cause and effect is increasingly difficult to trace; that change (planned or otherwise) unfolds in non-linear ways; that paradoxes and contradictions abound; and that creative solutions arise out of diversity, uncertainty and chaos.

Excellence is the asymptotic state that never quite reaches perfection.

Change is easy to propose, hard to implement, and especially hard to sustain.

Sustainable leadership does no harm to and actively improves the surrounding environment.

There is no morality without temptation; otherwise it is just lack of opportunity.

On being: Arrogance is not the prerogative of the gifted.

Sustainable leadership does not compromise the future by expanding and accelerating too quickly in the present.
