Leaders are not infallible.  Given the scope of their work and the magnitude of their decisions it goes without saying that a few mistakes are inevitable every now and then.  Mistakes, however, should not be used to de-value one’s sense of self-worth. Even the most soundly planned and researched business deals and projects may not succeed. Attitude, perseverance, and resilience are crucial to weathering the storm of undesirable outcomes.

“Failure is success if we learn from it.” ~ Malcolm Forbes

When failure happens analyze the mistakes by identifying the source of the issue. Encourage your team to do the same.  It is important to remember that the source of a problem is not always personal weakness. Learn from your mistakes and move on to the next opportunity. This approach will help keep your self-confidence intact.
