Leadership is no longer about your position, it’s more about your passion for excellence and making a difference. It’s the execution that takes focus, effort, discipline and patience. In business, if you take care of the relationship the money will follow. If you obsess about giving customers 10 times the value they expect, they will beat a path to your door. That’s what this rule you mention is all about; remembering to wow customers, and teammates, every time you have the privilege to encounter them.
An important subject for leaders to study is rationality, I mean being able to correctly conclude a rational, sensible course based on information. As a leader it’s also important to let everybody around you be helpful, but then put that through your own mental computer and make sure what you do is the product of what you’ve concluded based on all the input. I think developing rationality based on all the input is a true sense of leadership.
