In an ever changing world, you never learn it all, even if you keep growing into your 90s.

Good communication does not mean that you have to speak in perfectly formed sentences and paragraphs. It isn't about slickness. Simple and clear go a long way.

Overcoming complacency is crucial at the start of any change process, and it often requires a little bit of surprise, something that grabs attention at more than an intellectual level. You need to surprise people with something that disturbs their view that everything is perfect.

A leader needs enough understanding to fashion an intelligent strategy.

This is true even in organizations that are very focused on analysis and quantitative measurement, even among people who think of themselves as smart in an MBA sense. In highly successful change efforts, people find ways to help others see the problems or solutions in ways that influence emotions, not just thought.

Leadership is different from management, but not for the reasons most people think.

Leaders establish the vision for the future and set the strategy for getting there; they cause change. They motivate and inspire others to go in the right direction and they, along with everyone else, sacrifice to get there.
