The most important ratio for a leader is not debt to equity, supervisor to employee, efficiency to cost, or price to earnings. The ratio that matters most for leadership success is the proportion of praise to criticism.
Leadership at its core is about making people and situations better. To help a colleague improve, leaders can emphasize what they believe the team member should amplify or do more of, or what they should do differently. Getting a colleague to do more of what they already do is all about positive reinforcement, such as praise, encouragement, compliment, and applause. To encourage others to do things differently, leaders turn to feedback, criticism, advice, and suggestion.
