Management is formal authority given from above. Leadership is moral authority given from below and all around.

Internal victories precede external victories.

As human beings, we are responsible for our own lives. Our behavior is a function of our decisions, not our conditions. We can subordinate feelings to values.

Strength lies in differences, not in similarities

Communication is the most important skill in life. We spend most of our waking hours communicating. But consider this: You've spent years learning how to read and write, years learning how to speak. But what about listening?

Retire from your job but never from meaningful projects. If you want to live a long life, you need eustress, that is, a deep sense of meaning and of contribution to worthy projects and causes, particularly, your intergenerational family.

We can never really change someone; people must change themselves.
