Conventional wisdom is no wisdom at all. Conventional wisdom is taking somebody else's word for the way things are It's the followers of this world who rely on assumption. Not the leaders.

Change hurts. It makes people insecure, confused, and angry. People want things to be the same as they've always been, because that makes life easier. But, if you're a leader, you can't let your people hang on to the past.

What drives me? In every mission I'm on, the thing that drives me most is the desire to find my limits-and extend them.

Pain was their body's way of telling them that they'd pushed themselves to their limits - which was exactly where they were supposed to be.

The rules of war and business are the same. Victory and success are the same. In one it's life and/or death in the other it is success or failure. There really is little room for compromise of "gray matter".

Popularity is not leadership.

There is only one kind of failure I cannot tolerate: the failure to risk failure.
