My challenge is to make sure the things I say and the things I do remain consistent for as often and as long as possible. My why is to inspire people to do the things that inspire them so that together we can change our world. That's why I wake up every single day. I'm agnostic to the form it takes: I teach, I write, I speak, I advise.

A great leader will never sacrifice the people for the numbers.

What you do simply proves what you believe.

The most effective leaders are actually better at guarding against danger when they acknowledge it that it exists. Cowards, in contrast, cling to the hope that failure will never happen and may be sloppy in the face of danger - not because they don't acknowledge that it exists, but because they are just too afraid of it to look it in the eye.

In the 1980s America reacted to the Soviet Union's invasion of Afghanistan. We supported a war that left a nation torn to pieces. And as the last Soviet tank left the country, so did we.

Pure pragmatism can't imagine a bold future. Pure idealism can't get anything done. It is the delicate blend of both that drives innovation.

Leadership is neither a rank nor a title. It is a choice. The choice to provide care and protection for those for whom we are responsible.
