Some people seem as though they were born with many of the qualities required to be a good leader; but the reality is that most of us need to work at being a good leader by continually developing our skills. As a natural part of our growth and development process, we are bound to make mistakes; and even the most seasoned leader can sabotage their success by losing focus and stepping on a destructive "land mine." Mistakes can certainly be detrimental to your success; and some mistakes can effectively end your career if you are not careful.
