Leadership defines what the future should look like, aligns people with that vision, and inspires them to make it happen despite the obstacles.

Effective leaders help others to understand the necessity of change and to accept a common vision of the desired outcome.

Great leaders understand that historical success tends to produce stable and inwardly focused organizations, and these outfits, in turn, reinforce a feeling of contentment with the status quo.

People change what they do less because they are given an analysis that shifts their thinking than because they are shown a truth that influences their feelings.

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