It is very easy to lead and maintain a positive work environment when things are going well. It is easy to be relaxed and enjoy working with your team when there are no threats or fires to address. But, as Mike Tyson so eloquently put it, the moment things go haywire, is the moment one's workplace culture is tested.
Whether it be something small like a negative comment, a bad review, a customer complaint, or something sever like a major investor pulling out, a critical member of the team taking leave, or a decision by executive to make major changes to the department; big or small, every issue tests the capacity of one's leadership abilities when under pressure.
Failure is not something we avoid. Throughout our lives, personal and professional, we have or will face trials that challenge us. Our courage and tenacity isn't measured by whether we succeed or fail. And it sure as sh*t isn't measured by onlookers who compliment or insult us for our decisions in a time of a crisis. The true measure of our strength comes from how we take failure and growth because of it, not in spite of it. You are amazing because you are human and because you are flawed. It's what makes you exactly what the world needs to have in it to be a better place.
