The essence of leadership is to value the success of others over self. It is born out of the character of a person who is genuinely humble and incredibly grateful. This allows them to accomplish great things through empowering others because they do not want the credit. This HBR post is a great read:
“Two leaders walk out of a meeting. One just closed a major account and the other congratulates him for the win. Once the congratulator is out of earshot, the closer turns to his colleague and says, “He was green with envy before, and now he’s sucking up to me because he wants in on my account. He wants all the glory, but I worked hard for it. Now he knows how he makes the rest of us feel when he brags about his cushy life.”
