Leaders set the pace and tone for the organizations that they lead in many different ways. Your example creates a culture. Our habits, patterns, and actions permeate throughout our group. Leaders who are in the habit of being generous will generally end up building exceptionally generous organizations. But leaders who work long hours themselves create a culture glorifying the work of brutally long hours. Leaders who are hard on their subordinates will often create middle managers who are even harder on their subordinates. Encouraging positive mental health isn't the same as discouraging hard work. Instead, good mental health will increase the resilience of your workforce.
