Over the past three years, I have been stopped on the street by great folks telling me their own stories: How they didn't back down from the sharks, how they didn't ring the bell, or how making their bed every morning helped them through tough times. They all wanted to know more about how the ten lessons shaped my life and about the people who inspired me during my career. This small book is an attempt to do so.

They do what needs to be done, whether ordered to do so or not. This sense of initiative separates the great leaders from the mediocre ones.
