Without integrity, what do you have? Having a well-grounded set of principles and sticking to them demonstrates to the world — perhaps more importantly, shows you — what you are made of.

“If you have integrity, nothing else matters. If you don’t have integrity, nothing else matters.” — Sen. Alan Simpson



This is one aspect of leadership where you get ZERO redos. It only takes one tiny episode where you demonstrate a lack of integrity and that's how everyone remembers you. And that's how it should be.
