What is one of the worst things leaders can do?

Expend energy trying to make others think they're perfect is detrimental for a leader because it fosters an environment of dishonesty and distrust. When leaders present themselves as infallible, they create a barrier between themselves and their team. This facade prevents open communication and can discourage team members from sharing their own ideas or admitting mistakes, which are crucial for growth and innovation.

In leadership, it is vital to demonstrate vulnerability and authenticity. Recognizing one's imperfections helps to humanize a leader, making them more relatable and approachable. This creates a culture where team members feel comfortable sharing their input and learning from errors, ultimately leading to a more engaged and cohesive team. Focusing on an illusion of perfection detracts from the collaborative spirit necessary for effective leadership and can hinder the team's overall performance.
