A good leader focuses on making everyone else better.
Often in business the best version of others don't necessarily fit the job description they were hired for. But a clear, well communicated departure of the professional relationship will likely make both sides better going forward.
Adding value to others always comes back to you.
From book Trillion Dollar Coach by Eric Schmidt, John Rosenberg and Alan Eagle:
When Brad Smith took over as CEO of Intuit, Bill told him that he would go to bed every night thinking about those eight thousand souls who work for him. What are they thinking and feeling? How can I make them the best they can be? Ronnie Lott says, when talking about two coaches he worked closely with, Bill Walsh and Bill Campbell: “Great coaches lie awake at night thinking about how to make you better. They relish creating an environment where you get more out of yourself. Coaches are like great artists getting the stroke exactly right on a painting. They are painting relationships. Most people don’t spend a lot of time thinking about how they are going to make someone else better. But that’s what coaches do. It’s what Bill Campbell did, he just did it on a different field.”*
“What keeps you up at night?” is a traditional question asked of executives. For Bill the answer was always the same: the well-being and success of his people.
